摘要：
We have measured the effects of submonolayer oxygen adsorption on laser-induced Ga0 and Ga+ emission from GaP(110) surfaces. It is found that oxygen adsorption enhances that component of the Ga0 emission yield which decays rapidly as irradiation is repeated, but not the Ga+ emission yield. The results are interpreted in terms of bond weakening due to the interaction of surface defects with adsorbed oxygen.
