THE ELECTRICAL AND ELECTROCHEMICAL PROPERTIES OF GOLD-PLATED INP

The electrical properties of InP/Au dry contacts and the influence of electrodeposited gold on the electrochemical properties of InP electro des were studied. From current and impedance measurements on InP/Au dr y contacts it is concluded that the chemical composition of an interfa cial layer strongly influences the electrical characteristics. Further more, interface states are shown to play an important role. The interf acial layer and the interface states also determine to a large extent the electrochemical properties of the gold-plated electrodes.
