context_page_description: Abdulaziz Karimov is an Uzbek researcher in the field of semiconductors. He is the author of more than 40 patents and inventions in semiconductor optoelectronics. Doctor of Science Certificate for his research “Physical phenomena in GaAs-structures with thin quasiperiodic transition”. Professor in the field of Physics of semiconductors and dielectrics.
context_section_description: His work is the study of physical phenomena and processes in epitaxial multilayer structures and the development of their physical foundations. The scientific activity of Dr. A.V. Karimov  is closely related to the investigation of physical phenomena and processes in epitaxial multilayer structures and development of their physical basics as well as creation of a novel class of semiconductor devices. In 1980 Dr. A.V. Karimov was granted his PhD Certificate for his research titled “Development of physical basics of technology of production of GaAs-structures for field transistors and investigation of their thermal and photoelectrical properties”. His research was primarily devoted to the problems of obtaining the semiconductor epitaxial layers and properties of semiconductor structures on their basis. In 1991 he was granted the title of a senior scientific researcher. His scientific activity at the Physical-Technical Institute is connected to studying the physical phenomena and processes that take place in epitaxial multilayer structures and development of their physical basics, creation of a novel class of samples.
  In 1995 Doctor A.V. Karimov was granted his Doctor of Science Certificate for his research “Physical phenomena in GaAs-structures with thin quasiperiodic transition”. In 2006 he received the title of professor in the field of Physics of semiconductors and dielectrics.
  He has published more than 450 scientific articles, two monograph and one academic  textbook and invented - author more than 40 devices. Under his leadership, the physical basis of technologies have been developed, as well as the original design of multi-barrier photodiode structures with internal photoelectric amplifications. Invention three-barrier photodiode Karimov.
  He discovered that double-barrier rAlGaInAs-n GaAs-Au-injection structures and field effects are the basis of injection-field photodiodes with an operating voltage spectral range of A.
  His research results have been published in Technical Physics Letters, Radioelectronics and communications systems, Journal of Semiconductor Physics, Quantum Electronics, Optoelectronics and Journal of Engineering Physics).
  Noteworthy results include the spectral characteristics of the double-barrier structure with a corrugated surface of the photodetector as well as sensitivity to the impurity region of the spectrum.
  In comparison with the classical single-barrier photodiode, he obtained high values of photosensitivity from 5 to 15 A / W, which is one - one and a half orders of magnitude higher than (0.5-1 A / W) in the known analogues.
  Dr. A.V. Karimov regularly participates at various  part in high-profile international scientific conferences,  including lectures and  latest publicationsin in Prague, 13–17 October 2002, Berlin, 23–25 June 2003, Paris, 7–11 June 2004, Kiev and Odessa 2004-2007 at international conferences physical processes in phototransformator, photodiodes, phototransistors, and the problems of the physical processes in the pn-junctions. He was a member of the organizing committee of the conference held in Baku and Odessa (2004-2007 biennium) on Information and electronic technologies.
  Dr. A.V. Karimov was an active participant as a research manager of international projects UZB-31 “Development of solar energy photoconverters based on novel structures: ion-beam modified and diamond-like layers of polycrystalline silicon” (01.04.2000-31.06.2002), and UZB-56(J) “Development and investigation of micro-layer photoconverters with InGaAs/GaAs and AlGaAs/GaAs heteroepitaxial junctions” (01.10.2002-31.12.2004) jointly ith Ukrainian Science and Technology Center.
  The physical basics of the technology and original designs of multiple barrier photodiode structures with internal photoelectrical amplification were developed under his guidance in Uzbekistan in the early 90th [Karimov A.V.
