“…In recent years, transparent thin films of conductive oxides (TCOs), such as PbO , CdO, ZnO, SnO 2 , In 2 O 3 , and MoO 3 , of semiconductor materials have been used in various applications, including transistors, optical storage devices, gas sensors, phototransistors, and photo-thermal and photovoltaic converters [1,2]. Most of the studies related to transparent conducting metal oxides were performed on anion deficient (oxygen deficient) materials and, hence, always produced n-type conductors [3,4]. It is well known that high carrier mobility (μ H ) is essential for manufacturing TCOs with good electro-optical properties [5].…”
