Abstract :
We present systematic studies of the current-voltage characteristics of palladium Schottky diodes on ZnO layers grown on GaAs and demonstrate the advantages of using GaAs as a substrate. In terms of possible applications of the Pd/ZnO/GaAs system for gas sensing devices, transparent electronics and optoelectronics we study the sensitivity of these devices to hydrogen gas and light.
