Disordered Semiconductors Second Edition

Anatoly Popov is a professor at the Moscow Power Engineering Institute (MPEI), National Research University, Russia, since 1985 and has held positions of the dean of the electro-technical faculty, the first vice-rector, and the head of the Department of Semiconductor Electronics of the institute. He is also principal research scientist in the Institute of Nanotechnology of Microelectronics of the Russian Academy of Sciences and deputy chairman of the Council on Electronics and Telecommunications of the Higher Attestation Commission of Russia. He has also been an academic visitor to Fudan University, Shanghai, China, and an invited lecturer to the Samsung Advanced Institute of Technology, South Korea. He is author or co-author of more than 250 papers published in scientific journals or presented in international conferences and of 6 books on non-crystalline semiconductors. He holds patents of more than 20 inventions. His scientific interests lie in the exploration of the relationship between atomic structure and physical properties of disordered semiconductor materials and in the development of optical storage and electrical memory devices based on these materials.
