摘要
We have investigated structural and electrical properties of hydrogen (H)-doped In2O3 films fabricated by crystallization of the amorphous phase. To fabricate H-doped amorphous films, H2O vapor has been introduced into a sputtering system during the deposition of In2O3 without substrate heating. The films fabricated by solid-phase crystallization at 200 C have larger grains and lower strain than films fabricated by vapor-phase crystal growth. The resulting H-doped In2O3 films show very large mobility of 130 cm(2)/V s with resistivity of 2.7 x 10(-4) Omega cm. The high mobility in the films is ascribable to suppression of grain boundary defects as well as multicharged and neutral impurities. (C) 2007 Elsevier B.V. All rights reserved.
