Abstract

The characteristics of metal-insulator-semiconductor (MIS) and junction thin-film device structures utilizing phosphorus-doped ZnO materials were examined. The capacitance-voltage characteristic of the MIS diode structures were measured in order to delineate the carrier type in the (Zn,Mg)O:P film. The I-V curves for reverse bias and strongly forward bias were nearly linear functions, suggesting the presence of a series resistance and reverse bias leakage conductance. The p-type symmetry was found to be highly dependent on the process and annealing conditions.
