Doctor Hubilitate Ghenadii Korotcenkov is Chief Scientific Researcher, Moldova State University, Chisinau, Moldova. He has more than 50 years of research experience in the field of materials science and the development and research of various devices based on semiconductor materials. Until 1995 he studied Schottky barriers, MOS structures, native oxides, and various photoreceivers based on III–Vs compounds such as InP, GaP, AlGaAs, and InGaAs. His current research interests since 1995 include material sciences, focusing on metal oxide film deposition and characterization (In2O3, SnO2, ZnO, TiO2), surface science, thermoelectric conversion, and design of physical and chemical sensors, including thin film gas sensors. G. Korotcenkov is the author or editor of 48 books and special issues published by Momentum Press, CRC Press, Springer (USA), Harbin Institute of Technology Press (China), Trans Tech Publication (Switzerland) and EDP Sciences (France). Currently he is a series editor of “Metal Oxides” book series published by Elsevier. Since 2017, more than 40 volumes have been published within this series. G. Korotcenkov is the author and coauthor of more than 675 scientific publications, including 42 review papers, 70 book chapters, more than 250 peer-reviewed articles published in scientific journals (h-factor=45 (Web of Science), h=47 (Scopus) and h=72 (Google scholar citation), 2024). He is the holder of 17 patents. His scientific work has been recognized with numerous awards, including the National Prize of the Republic of Moldova (2022), an Award of the Academy of Sciences of Moldova (2019), the Prize of the Presidents of the Ukrainian, Belarus, and Moldovan Academies of Sciences (2003), the National Youth Prize of the Republic of Moldova in the field of science and technology (1980), and others. G. Korotcenkov have been listed as one of the "World's Ranking Top 2% Scientists" in Applied Physics/Analytical Chemistry in the Physics and Astronomy Cluster. G. Korotcenkov also received a fellowships from the International Research Exchange Board (IREX, United States, 1998), Brain Korea 21 Program (2008-2012), and BrainPool Program (Korea, 2007-2008 and 2015-2017).
