Abstract
An experimental study of Au‐polycrystalline GaAs Schottky barriers has been made. The current‐voltage and capacitance‐voltage characteristics of GaAs films of various grain sizes have been measured. Analysis of these data indicate that the transport may be electrode‐limited, bulk‐limited, or a combination of electrode‐limited and bulk‐limited conduction processes, depending upon the (average) grain size.Keywords
