2D SiC/Si Structure: Electron States and Adsorbability

A model of a heterostructure consisting of a silicon-carbide single layer formed on a massive silicon substrate is proposed. The problem of the adsorption of alkali metal atoms and halogen atoms on the carbon and silicon surface atoms of a 2D SiC/Si heterostructure is considered. Analytical estimates for charge transfer and the adsorption energy are reported.
