Abstract:
The Schottky barrier height and ideality factor of Ti on p-type strained-Si (grown on a graded relaxed Si0.82Ge0.18 buffer layer) were investigated in the temperature range 200–300 K using the current-voltage (I-V) characteristics and were found to be temperature dependent. While the ideality factor decreases with an increase in temperature, the barrier height increases.
