Abstract

Tin oxide having high mobility and a low electron concentration, and methods for producing layers of the tin oxide layers on a substrate by atmospheric pressure chemical vapor deposition (APCVD) are disclosed. The tin oxide may undoped polycrystalline n-type tin oxide or it may be doped polycrystalline p-type tin oxide. When the layer of tin oxide is formed on a crystalline substrate, substantially crystalline tin oxide is formed. Dopant precursors for producing doped p-type tin oxide are also disclosed.
