Experimental results give rise to many applications as gas sensing and solar cells for tin oxide when it is doped by Sb, Ag and Pt. The band structure and the gap change in value and give this doped compound good properties in the fields of photon detection, electrical conduction and optical transmission;

Lowest band is split with element doping due to the strong hybridization with dopant s-type states and this splitting contributes to both the decrease of the plasma frequency and the mobility of the carriers.
