Opto-Electrical Interactions in Next Generation Semiconductor Thin Films and Devices
Authors:   , Kerremans Robin
Published: November 2021

The processes by which optical and electrical energies are transduced are at the heart of many modern technologies such as solar cells, light emitting diodes, photodetectors, imaging systems and displays. The basic functional element of these ‘opto-electrical’ devices are semiconductors, and the underpinning physics of how they transduce light and electricity is well understood for conventional inorganic materials such as silicon and gallium arsenide. However, new semiconductors such as the organics and the organohalide perovskites present additional opto-electrical questions and challenges since they are molecular solids with varying degrees of disorder and crystallinity. The work described in this thesis addresses these new questions and challenges, particularly in relation to how existing solid-state physics concepts must be adapted to reliably predict and model material-and-device-level structure-property relationships and performance. Two basic technology platforms are examined in detail – solar cells and light emitting diodes, with particular reference to so-called reciprocity. A second focus of the discussion is accurate determination of optical constants for these new semiconductors – a challenging endeavour due to factors such as morphological heterogeneity. Transfer matrix and drift diffusion formalisms are relied heavily upon to model, simulate and explain multi-layer device performance, and ellipsometry and spectrophotometry are utilised as the primary analysis and characterisation methodologies. A new approach to optical constant determination is presented and validated, as is an adapted reciprocity framework for the linking of absorption, emission and charge transfer state characterisation in the presence of cavity interference. Several ‘difficult’ solar cell systems are analysed in detail – in particular the previously mysterious working principles of the so-called carbon-stack perovskite system are elucidated for the first time. These findings explain how an electrically non-selective contact can still function as an effective photovoltaic electrode dependent upon the local minority and majority carrier concentration profile. The research described herein advances our understanding of next generation semiconductor opto-electrical physics and provides more practical means for the community to analyse optical constants.

Authors: Jiménez Rivas José Ramón , Morita Alexander Adelina
Published: November 2021

Desde hace muchos años, los factores que afectan el desempeño académico han sido estudiados en el ámbito interescolar, local, estatal, nacional e internacional, tanto en instituciones públicas como privadas. Determinar cuál de ellos prevalecen en los estudiantes con mejores logros podría coadyuvar a una mejor enseñanza. Existen indagaciones enfocadas en cómo los factores personales influyen en el aprendizaje; sin embargo, hay poca literatura acerca de su impacto en el desempeño de lengua extanjera. Por tanto, este trabajo se centró en estudiar si algún factor personal (edad, género, o perfil de autodirección del estudiante) guardaba relación con el desempeño académico en la materia Lengua Extranjera, que pertenece al currículo del primer año de una universidad pública localizada al norte de la Ciudad de México. El estudio tuvo un enfoque cuantitativo y un diseño de investigación transversal, descriptivo y correlacional. La muestra elegida por conveniencia estuvo conformada por 39 estudiantes de ambos sexos. El instrumento utilizado para medir el perfil de autodirección fue el cuestionario de indagación de perfil autodirigido. Dicho instrumento consiste en 50 ítems, con escala Likert de cinco puntos, y con confiabilidad de 0.90 en el índice alfa de Cronbach. Con los factores personales seleccionados, la edad de los estudiantes, mayoritariamente adultos jóvenes (mujeres, 24.3 años; hombres, 25.92 años) se encontró un coeficiente de correlación de Spearman rs = .101, p < .540 N=39. Con el género (la muestra estuvo conformada por 66.7 % mujeres y 33.3 % hombres), la correlación de Pearson fue r =-.387, p < .015 N=39. Finalmente, pese a que los participantes tuvieron un muy buen perfil de autodirección, según el instrumento utilizado, la correlación indicó rs=-.054, p < .744 N=39. A partir del análisis estadístico, se demostró que la interdependencia entre los mencionados factores personales y el desempeño académico es estadísticamente no significativa.

The article considers the influence of precursor type and sol-gel synthesis conditions of TiO2 on its properties. The obtained TiO2 samples were characterized by X-ray diffraction methods, electron microscopy, as a result of which it was found that all the obtained TiO2 powders have the crystallite size in a nanorange of 2.5–17 nm. It was shown that sorption-photocatalytic properties of TiO2 significantly depend on a phase composition, surface acidity, specific surface area and porosity. It was found that the amorphous TiO2 has improved adsorption properties, while crystalline TiO2 is characterized by enhanced photocatalytic properties. Determined acidic nature of the TiO2 surface explains the better sorption and photocatalysis relative to the cationic dye.

The article presents simple kinetic approaches to study the effect of multi-walled carbon nanotubes (MWCNTs) additives on the aerobic oxidation of hydrocarbons and to propose real acceptable mechanisms of the process. The aerobic liquid phase low-temperature oxidation of ethylbenzene conducted in the presence of multi-walled carbon nanotubes has been used as a model pattern. Kinetic analysis established the catalytic action associated with the presence of the iron compounds in inner channels of MWCNTs. These compounds are identified as ferric carbides provoking decomposition of the ethylbenzene hydroperoxide and thereby suppressing the competitive route of alky-peroxide radicals addition to the nanocarbon cage. Thus the reaction finally proceeds in the autocatalytic mode.Contradictory conclusions on the effect of CNTs on the oxidation chain processes existing in the literature are associated with the lack of control over nature and content of metal impurities in channels of nanotubes.

The investigation data of the formation peculiarities of oxide films on the Ti6A14V alloy in tartaric acid solutions have been given. It is shown that the behavior of alloy forming dependences is conditioned by the anode current density. At ja < 0.5 A∙dm-2 the continuous oxide film is not formed on the alloy surface and the preset value of the final voltage on the cell is not reached. With an increase in ja > 0.5 A∙dm-2, alloy forming dependences show a linear behavior that is indicative of the formation of low porous films. In these conditions, the oxide film formation rate is in direct proportion to the value of ja. The electrochemical oxidation of Ti6A14V alloy in tartaric acid solutions results in the formation of interference-colored oxide films. The oxide film ultimate thickness and color are defined by the preset voltage and are independent of the current density and electrolyte concentration. The isolating properties of obtained films were studied by the way of the cathode polarization of oxidized specimens in the sulfate copper-plating electrolyte. The research done allows us to make a conclusion that electrochemical copper deposition is a convenient tool for the detection of defective spots in oxide films. It is shown that due to the specific features of the reduction kinetics of Cu2+ ions on the oxidized titanium it is reasonable to use for the studies the initial sections of polarization dependences that correspond to ΔE = 0.2–0.25 V. The alloy polarization dependences allow us to establish unavailability of apparent dependences between the oxidation current density, the electrolyte concentration, the cell final voltage value and the polarization that occurs during the Cu2+ ion reduction. The anodic connection of copper-coated specimens conditions the reversible dissolution of a greater portion of the specks of copper deposits. It is indicative of the electron conduction of film defects. The obtained data allow us to vary the electrolysis parameters in a wide range with no significant influence of the treatment mode of Ti6A14V alloy on the quality of oxide coatings.

Monomolecular films of diacyl diperoxides at the water–air phase interface have been studied. Their behaviour is influenced by the structure of the molecule and the solvent. The numerical values of the areas of molecules that are extrapolated to zero pressure are different, which indicates a different conformation of the molecules in the monolayer. The conformational states of diperoxides were calculated by quantum chemical methods. Experimental data and quantum chemical calculations are consistent with each other.

Polymeric composites (PC) of tribological applications with a high level of physical, mechanical and thermal properties based on aromatic polyamide and silica gel have been developed. Regularities have been obtained that describe the effect of the filler content in PC on the friction coefficient, temperature on the friction surface and the intensity of linear wear rate of the studied PC-steel friction pair. It was found that the optimal silica gel content in the polymer matrix is 10 wt %. The morphology of the steel surface of friction after friction interaction with PC based on aromatic polyamide and silica gel was studied. The formation of an antifriction film on the steel surface of friction was discovered, which contributes to a decrease in the friction coefficient, temperature on the friction surface, and the linear wear intensity of the studied PC. The influence of the load and sliding speed on the main tribotechnical characteristics of the PC-steel friction pair has been studied. Mathematical laws were derived that describe the influence of the main external factors (load and sliding speed) on the friction coefficient and intensity of linear wear rate of the studied friction pair. Physical, mechanical and thermal investigations of the developed PC were carried out and it was found that the introduction of 10 wt % silica gel contributes to their 5–10 % increase.

Sputtering of PbTe, SnTe, and GeTe crystal samples by low-energy Ar+ ions are investigated, and the sputtering rate vsp of the studied compounds, as well as its dependence on both the composition of crystal matrix and the sputtering energy are determined. It is found that under the same conditions the sputtering rate in the sequence of GeTe-SnTe-PbTe telluride compounds increases when their average atomic weight increases. This phenomenon is explained by changes in the surface binding energy of metal atoms in lead, tin and germanium tellurides. It is shown that for all compounds the sputtering rate also increases with the increase in the sputtering energy. In the energy range from 160 to 550 eV,this increase is almost linear. The coefficients of change in the sputtering rate with energy dvsp/dE are calculated. The surface density of Ar+ ion-induced structures and the relative area of the sputtered surface covered by these structures are determined for the natural lateral surfaces of a PbTe crystal grown from melt by the Bridgman method as a function of sputtering energy. It is shown that both studied parameters decrease exponentially with increasing the sputtering energy.

According to the results of the study, it has been established that chronic acetylsalicylic acid poisoning results in severe liver disorders presented by both venous and portal blood overloaded with a reflex throughput decrease of the arterial part of the bloodstream. Prolonged venous stasis and reflex vasoconstriction of arteries lead to ischemia of the liver tissue with the development and progression of dystrophic changes in hepatocytes. With an increase in the duration of observation, there is an expansion of cell zones with signs of granular dystrophy, which pass into fields with dystrophy of hepatic cells, damage of intercellular boundaries, homogenization of cytoplasm and degradation of nuclei of hepatocytes. It was manifested quantitatively by an increase in the cross-section of hepatocytes and their nuclei with an appropriate dynamics of nuclear-cytoplasmic relations.

According to the experimental study on Vietnamese pigs after implantation of a polypropylene mesh with PRF membrane into retromuscular space, the results of ultrastructural changes in the cells of muscular aponeurotic layer of abdominal wall were presented. It was proved that on the 14th day of the experiment, inflammatory changes in tissues were expressed significantly less than in cases of the isolated implantation of the polypropylene mesh without PRF membrane. Activation of fibroblasts and signs of fiber structures development around the mesh material increased. In the late experimental period (28 days), at the microscopic and electron-microscopic levels the minor manifestations of inflammatory reaction, improved microcirculation in the area of implantation of the mesh with PRF membrane were found that in turn contributed to the increased activity of fibroblasts and development of collagen fibers around the mesh material. The use of PRF plasma membranes stimulated an active development of new capillaries, improved blood flow, accelerated metabolic processes in tissues, and suddenly increased development of collagen, hyaluronic acid that in turn created favourable environment for a complete integration of the polypropylene mesh into the muscular aponeurotic layer of anterior abdominal wall tissue.

The components of the hepatoduodenal ligament play an important role in the process of digestion. Calculi in the common bile duct are found in 10-15% of individuals suffering from chronic calculous cholecystitis, and obstruction of bile ducts is found in 59,1-67,4% of cases. The objective of the study was to investigate peculiarities of component morphogenesis of the hepatoduodenal ligament during the perinatal period of human ontogenesis, individual and age anatomical variability, spatial-temporal transformations, and anatomical-histological peculiarities of its structures. To achieve the stated purposes the following complex of methods was used: macroscopic – for visual detection of the state of the hepatoduodenal ligament components, vascular injection – to study peculiarities and variants of angioarchitectonics of the arterial components of the hepatoduodenal ligament, statistical – to determine peculiarities of morphological transformations of the components and adjacent structures of the hepatoduodenal ligament at different periods of prenatal and postnatal periods of human ontogenesis. According to the results of the study several accessory triangles of the hepatoduodenal ligament were found and described. The common bile duct, the common hepatic duct, cystic duct, left and right hepatic ducts, hepatic portal vein, common hepatic artery, right gastric artery, hepatic artery proper, right, left and accessory branches of the hepatic artery proper are permanent components of the ligament forming a number of combinations-crossings between themselves.  Meanwhile, we have determined certain regularities of the formed pattern including minimum 5 permanent triangles to be distinguished: Calot’s triangle or "superior lateral triangle", "superior medial triangle", "inferior medial triangle", "inferior lateral triangle", "central space of the hepatoduodenal ligament".

Abstract: In the course of the history of Islamic education,Islamic schools as institutions of Islamic education was not as expected. One side, in terms of religion, alumni are not able to compete with graduates of boarding schools and on the other hand, in terms of general science, can not compete with public schools. So too, madrasas in education and learning are not in line with communitlr interests, and can not solve the problems faced by society. There has been a "dehumanization" in the practice of education in madrasas. Therefore, to liberate the madrasa education from the process of "dehumanization", as well as for education in accordance with the interests of society, the madrasa education should be society-based (popular) to instilt a spirit critical of social phenomena. Therefore, the critical educational needs in the learning process, cooperation between the madrasas with the community and always do the renewal of the retigious doctrines which have been shallowed.

This condition was by done by the Old Oder and News Order in order to transform the ideology. Education tries to transform knowledge in the area of reconstruction, especially the reconstruction of culture to position a new value system. With the change in the framework of human thought, the concept of culture itself will shift. Here, the importance of education as a system of meaning that is not binding (the process of liberation), humanizing, and caviling process. This will be done properly if there is critical thinking about  methodology, social structure, the rules so that no further transformation.
