A scientific seminar was held at the Scientific Research Institute for Physical Problems of Baku State University (BSU) on October 28, 2021.

Muhammad Hasanov, researcher at the Department of Condensed Matter Physics made presentation entitled “Electrophysical properties of metal–semiconductor contact by the theory of complex systems”.

He noted that the purpose of this work is to analyze the electrical properties of the metal–semiconductor contact (MSC) in the framework of the theory of complex systems. The effect of inhomogeneity of the different microstructures: polycrystalline, monocrystalline, amorphous metal–semiconductor contact surface is investigated, considering a Schottky diode (SD) as a parallel connection of numerous subdiodes. It has been shown that the polycrystallinity of the metal translates a homogeneous contact into a complex system, which consists of parallel connected numerous elementary contacts having different properties and parameters.
