Abstract

The aim of this study was to improve the adhesion of Au Schottky contacts to SiC. In order to do this, before the deposition of the Au layer, a thin layer of Ti was deposited. However, this resulted in an anomalous step in the forward bias electrical characteristic for some diodes. An equivalent circuit model is introduced to explain this irregularity in terms of two barrier heights. PSPICE is used to simulate this model. Simulated and experimental data are in good agreement over the temperature range 25 to 250 degrees C. (C) 1999 Elsevier Science S.A. All rights reserved.
