Polycrystalline thin films of indium tin oxide sputter-deposited in the working gas containing hydrogen of 0.3-1.5% exhibited transmittance of >= 80% for visible lights and blue-shift of >= 0.1 eV in the optical absorption energy. The film deposited in the gas containing hydrogen of 1% demonstrated almost flat temperature-dependent resistivity and the lowest resistivity of = 1.5 x 10(-4) Omega cm at room temperature. The carrier density showed an inverse V-shaped behavior with the maximum at the hydrogen concentration of 1%. The mobility stayed at almost constant below the hydrogen concentration of 1% and dropped rather rapidly above 1%. (C) 2008 Elsevier B.V. All rights reserved.
