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 3С-, 6Н- and 4Н-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.
