Conductivity And Seebeck Coefficient In Granular Silicon

Аннотация

The article discusses the physical processes, the related temperature dependencies of conductivity and the Zeebek coefficient in granular silicon and the influence of alkali metal atoms on them at a temperature of 300 K to 800 K. that the conductivity and Zebeck coefficient do not depend only on temperature, it depends on the crystal structure at the boundary of the two contacting regions, and the development of recombination centers in them with an increase in temperature. In the process of temperature growth, desorption of alkali metal atoms is observed, which leads to structural inhomogeneities of crystal lattices at the border of two contacting regions and at the same time increase in structural heterogeneity of crystal lattices of the desorption layer of alkali metal atoms, lead to electron scattering, which leads to a change in sign.
