Abstract :
A new Pt/Al/n-InP contact diode which has a good l-V characteristic is studied. It has a barrier height of 0.74 eV which increases to 0.99 eV when it is treated with HF, an ideality factor of 1.18, and a reverse leakage current of 5.5×108 A/cm2 at -3 V. This good performance is believed to be due to the combined effects of the formation of an interfacial oxide layer and fluorine passivation on the surface
