Polycrystalline films of tungsten-doped indium oxide prepared by d.c. magnetron sputtering

Magnetoelectrical properties of W doped ZnO thin films

“…Although there are many studies assisting in optic and electrical effects of W atoms [7][8][9], magnetization was not a known subject for W doped wide band gap oxide semiconductors. On the other hand, the anomalous magnetic properties were known due to strong s-f exchange interaction in Eu-Chalcogenide Alloys [10].…”

Amorphous tungsten-doped In2O3 transparent conductive films deposited at room temperature from metallic target

“…The average transmittance from 400 to 2500 nm is relatively higher than conventionally sputtered polycrystalline ITO [9,10], whose transmittance curve declines evidently at wavelength over 1200 nm. It indicates that amorphous IWO have potential application in solar cells to transmit more long-wavelength radiation, as well as in energy-efficient windows installed in cold regions to transmit more sunlight into the room.…”

“…With the development of transparent electronics, much effort is underway to optimize TCO films. Lately reported polycrystalline molybdenum-doped indium oxide (IMO) [6,7] and tungsten-doped indium oxide (IWO) [8,9] thin films are attractive due to their high carrier mobility producing a low resistivity comparable to that of ITO films. In our previous work [10,11], investigations into carrier concentration, carrier mobility and transparency in the near-infrared region of polycrystalline IWO were carried out.…”

Effect of Tungsten Doping on the Properties of In2O3 Films

“…Tungsten with a lower ionic radius and higher oxidation state compared to In 3+ cation can be a good dopant for In2O3 lattice. It is reported that tungsten doped indium oxide films have high mobility, low electrical resistivity and high transparency in the visible and near infrared region [17][18][19][20][21][22]. Structural properties can affect the quality of thin films thereby modifying their optical, electrical, sensing properties etc.…”
