Abstract
Hydrogenation of an InP surface has been achieved by hydrogen plasma. Exposure in the limited temperature range 95-100 degrees C gives rise to a remarkable enhancement of the photoluminescence (PL) intensity by a factor of 5.4 compared with that of unexposed InP. On the other hand, a reduction in the PL intensity occurs at temperatures a little higher than 100 degrees C which leads to surface damage owing to preferential dissociation of phosphorus from the surface of InP. It is confirmed by secondary ion mass spectroscopy (SIMS) that hydrogen with concentration of 1*1018 cm-3 diffuses into the bulk InP down to a depth of 300 nm.
