Abstract

We report on n-type (100) oriented Si0.76Ge0.24 samples grown by silicon molecular beam epitaxy (Si-MBE). The grown wafer was, first, cut into small pieces. Some of these pieces were annealed under an inert gas atmosphere at 600 degrees C, 700 degrees C and 800 degrees C for 1 h to induce partial relaxation in Si1-xGex. The formation of Schottky junction was made by Pt deposition on n-Si0.76Ge0.24. The electrical properties of, both, the unannealed and annealed Pt/n-Si0.76Ge0.24/n-Si were studied by current-voltage (I-V) and capacitance-voltage (C-V) measurements. These measurements have been done under different temperatures, and Schottky barrier heights have been determined. Also, these results have been compared with Pt / n-Si.
