Abstract |
Zirconium-doped indium oxide (In2O3:Zr) thin films of various Zr-contens were hetero-epitaxially grown on a sapphire single-crystalline substrate by a magnetron sputtering method. The films were heat-treated in an N2 atmosphere and the variations of their electrical properties as a function of the Zr-content were investigated. We observed the resistivity decreasing without any deterioration in their crystallinity and optical transmission property after the heat-treatment when the impurity content was within 2 wt.%, and then, the degree of the resistivity-decrease saturated since their mobility started to decrease due to the heavy impurity doping. |
