Abstract:

The high-field behavior of the interface between a conducting CdS crystal and a blocking electrolyte contact is studied by the use of pulse techniques. The method employed is very suitable for determining the characteristics of the space-charge region at the crystal surface. In contrast to the case of d.c. measurements, where breakdown of the blocking contact is not apparent up to fields of at least 2x 10,000,000 Vcm, large transient currents through the interface are observed in the range 5 x 1,000,000 to 10,000,000 Vcm. These currents are ascribed to field emission from surface states into the conduction band of the CdS crustaystal. The surface states are shown to be intimately correlated with electrolytically deposited sulphur. Author
