Abstract

The Cr/n-GaAs/Cr and Ag/p-GaAs/Ag metal-semiconductor-metal (MSM) Schottky contacts have been fabricated by reactive radio frequency (RF) sputtering system. The current-voltage (I-V) and capacitance-voltage (C-V) characteristics of the devices have been investigated in the temperature range of 80-316 K for the back-to-back switched Schottky barrier contacts. These measurements establish that the room temperature barrier height determined from reverse branch of the current-voltage characteristics is close to the value obtained from capacitance-voltage measurements.
