Sensor Layers Based on Semiconductor Nanoparticles and Their Electronic Structure
Л. И. Трахтенберг
Abstract
Abstract Studies on modeling the charge distribution in semiconductor nanoparticles are analyzed. The charge distribution largely depends on the type of nanoparticles and the concentration of conduction electrons. In the case of nanoparticles with a high content of electrons in the conduction band, the negatively charged layer plays an important role. The conductivity and sensor effect depend on this layer. It is shown that both the distribution of electrons and the sensor effect differ significantly in one- and two-component systems. The reasons for this difference are discussed.
