摘要: Electrical, optical and magnetic properties of polycrystalline Cr-doped SnO(2) films grown on glasses using reactive dc magnetron co-sputtering technique were investigated. The Cr content was modulated by varying the sputtering power applied on the Cr target. The carrier concentration and conductivity of doped films are reduced with increasing the Cr doping. Moreover, while the Cr content ratio Cr/( Sn + Cr) exceeds 0.9 at.%, the doped SnO(2) films become insulators and the optical transmission is strongly affected. The surface roughness of sputtered films is also increased by Cr doping. The co-sputtered Cr-doped SnO(2) films exhibit paramagnetic characteristics from room temperature down to 25 K.
