Penelitian terhadap kinerja keuangan PT. DSFI yang dilakukan sebelum pandemic covid-19 pada tahun 2018-2019 dibandingkan dengan keadaan ketika terjadi pandemic covid-19 tahun 2020-2022, secara umum menunjukkan keadaan yang lebih baik. Hal itu terlihat pada keadaan likuiditas perusahaan yang diukur dengan Cash Ratio, Quick Ratio, dan Current Ratio. Kondisi solvabilitas yang diukur dengan Debt to Asset dan Debt to Equity juga menunjukkan keadaan yang lebih baik ketika pandemic terjadi. Hanya rasio aktivitas saja yang diukur dengan Perputaran Total Aktiva, Perputaran Total Persediaan dan Perputaran Piutang yang menunjukkan penurunan, hal ini dikarenakan terjadinya penurunan penjualan sejak tahun 2018-2020. Sedangkan kemampuan profitabilitas yang diukur dengan Return on Asset dan Return on Equity menunjukkan kecenderungan yang meningkat ketika pandemic terjadi. Walaupun kinerja ketika pandemic meningkat namun hal itu belum sesuai dengan standar industri. Secara umum kondisi kinerja PT. DSFI lebih baik setelah terjadi pandemic Covid-19 daripada sebelum pademic Covid-19.

AbstractHeight on the COVID‐19 pandemic (2020–2021), a considerable atmosphere of uncertainty and insecurity has emerged throughout the world. At the same time, social media and conspiracy theories have gained a lot of popularity. However, due to the impact of science and scientists on the public countering these sources of information, the outcome of the test given by science during the pandemic is still unclear. In this study, the relationship between trust in science and scientists, reliance on social media, belief in conspiracy theories, and pandemic awareness is modeled. A total of 953 adults from Turkey participated in the study and the obtained data were analyzed with the structural equation model. According to the results of the path analysis, reliance on social media influencers and belief in conspiracy theories affect trust in science both directly and indirectly. In addition, there is a positive relationship between pandemic awareness and trust in science.

Published: July 2023

AbstractActive thermal radiation control of an object requires adaptive and flexible strategies to cope with emissivity engineering and its temperature dependence. On the other hand, the concept of digital coding allows a high degree of freedom in manipulating the interacting physical quantities based on local discretized features. Learning from this idea, this study put forward the manipulation of spatial infrared emission based on tungsten (W)‐doped VO2 films toward thermal coding. Here, 1‐bit coding worksheets created by low‐emissivity, that is, code ‘0′, and high‐emissivity, that is, code ‘1′, shift with materials metal‐insulator phase transition to encode emissive information in the temperature domain. It is shown experimentally that this concept has marked implications on thermal radiation control at Mid‐infrared, among which are as follows: digital anti‐counterfeiting by in‐plane spatial coding of a group of VO2 thin films with various W‐doping density and infrared camouflage by out‐of‐plane spatial coding of them. With a W‐doping gradient of 0%, 0.8%, and 1.7%, the three‐phase transition points in the temperature domain, that is, 72, 63, and 45 °C, give a remarkable modulation range of 27 °C. These phenomena pave the way for new classes of emissivity engineering for more accurate, flexible, and adaptive thermal radiation control.

AbstractLight‐emitting transistors (LETs) are optoelectronic devices that perform switching and light‐emitting functions in a single device. Hybrid LETS (HLETs) using inorganic metal oxide semiconductors as the transport layer with organic emissive layers and hole‐injection layers (HILs) combine the excellent switching performance of metal oxides with the flexibility and tunability of organic semiconductors. However, the efficiency of n‐HLETs typically suffers from unbalanced electron and hole injection. To overcome this issue, two hybrid polyelectrolytes—lithium poly(styrene sulfonate) (Li:PSS) and copper(II) poly(styrene sulfonate) (Cu:PSS)—are investigated as HILs in HLETs. HLETs employing Cu:PSS interlayers exhibit significantly enhanced brightness values of up to 4.89 × 103 cd m−2 and an external quantum efficiency (EQE) of 0.45%, compared to HLETs without HIL (no emission) and pristine poly(3,4‐ethylenedioxythiophene):poly(styrene sulfonate) (PEDOT:PSS) (2.17 × 102 cd m−2 with an EQE of 0.01%). To understand how the HILs influence the performance, ultraviolet photoelectron spectroscopy (UPS) analysis and photoluminescence (PL) quenching studies are performed, which reveal improved energy band structure and reduced quenching using metal:PSS HILs. This work provides useful information about the function that polyelectrolyte HILs perform in HLET devices which may be exploited to develop new materials and applied in other types of optoelectronic devices.
Local Manipulation of the Energy Levels of 2D TMDCs on the Microscale Level via Microprinted Self‐Assembled Monolayers

Published: July 2023

Abstract2D transition metal dichalcogenides (TMDCs) are atomically‐thick semiconductors with great potential for next‐generation optoelectronic applications, such as transistors and sensors. Their large surface‐to‐volume ratio makes them energy‐efficient but also extremely sensitive to the physical‐chemical surroundings. The latter must be carefully considered when predicting the electronic behavior, such as their energy level alignment, which ultimately affects the charge carrier injection and transport in devices. Here, local doping is demonstrated and thus adjusting the opto‐electronic properties of monolayer TMDCs (WSe2 and MoS2) by chemically engineering the surface of the supporting substrate. This is achieved by decorating the substrate by microcontact printing with patterns of two different self‐assembled monolayers (SAMs). The SAMs posses distinct molecular dipoles and dielectric constants, significantly influencing the TMDCs electronic and optical properties. By analyzing (on various substrtates), it is confirmed that these effects arise solely from the interaction between SAMs and TMDCs. Understanding the diverse dielectric environments experienced by TMDCs allows for a correlation between electronic and optical behaviours. The changes primarily involve alteration in the electronic band gap width, which can be calculated using the Schottky‐Mott rule, incorporating the dielectric screening of the TMDCs surroundings. This knowledge enables accurate prediction of the (opto‐)electronic behavior of monolayer TMDCs for advanced device design.

AbstractHigh‐quality near‐ultraviolet/deep‐blue organic emitters are urgently needed but still rare. Here, three V‐shape donor‐acceptor‐donor (D‐A‐D) emitters based on pyrazine cores, namely, VDMP‐PhCz, VDMP‐36PhCz, and VDMP‐TPA, are designed and synthesized. Their doped devices using a high‐polar host show remarkable electroluminescence (EL) performances with maximum external quantum efficiency (EQE) values up to 7.37%, 7.55%, and 9.03%, and corresponding CIE coordinates of (0.160,0.040), (0.161,0.039), and (0.149,0.072), respectively. Supported by theoretical calculations and experimental results, the high EL performances of these emitters are achieved by their planarized intramolecular charge transfer (PLICT) features, high triplet‐excitons utilization from “hot exciton” channels, and high horizontal dipole orientations. Furthermore, these PLICT‐based emitters can also function as efficient hosts for green or yellow multi‐resonance (MR) narrowband emissive guests, providing high EQEs of over 32% with alleviated efficiency roll‐offs.
