摘要：
The electrical properties of composite oxide (anodized oxide and tantalum oxide deposited by reactive sputtering) on GaAs annealed in N2O were studied. The leakage current was decreased and at moderate electric field strengths it is governed by Schottky emission. The breakdown electric field of the samples and the dielectric constant of tantalum oxide were increased after annealing. (C) 1998 American Vacuum Society. [S0734-2101(98)03404-6].
