Abstract: Within the scope of the Haldane–Anderson model the estimates of charge transfer and adsorption energy for alkali metals and halogens atoms on the С- and Si-faces of 3$C$-, 6$H$- and 4$H$-SiC polytypes are obtained. Band and local states contributions to the formation of adatom's charge and ionic and metallic parts of the adsorption energy are clarified.

Keywords: adatom, charge transfer, adsorption energy.
