Abstract: Passivation of the liquid phase epitaxial GaAs surface was attempted using aqueous P2S5 -NH4OH (NH4)2Sx and plasma nitrogenation and hydrogenation. Results indicate that plasma nitrogenation with pretreatment of plasma hydrogenation produced consistent reduction in reverse leakage current at room temperature for all p and n type Schottky diodes. Some diodes showed an order of magnitude improvement in current density. (NH4)2Sx passivation also results in improved I-V characteristics though the long term stability of this passivation is questionable.
