Abstract
The effect of molecular nitrogen exposure on the InP(100) surface modi fied by the alkali metal K overlayer is investigated by core-level pho toemission spectroscopy using synchrotron radiation. The alkali metal covered surface exhibits reasonable nitrogen uptake at room temperatur e, and results in the formation of a P3N5 nitride complex. Flash annea ling at 400 degrees C greatly enhanced the formation of this kind of n itride complex. Above 500 degrees C, the nitride complex dissolved com pletely. (C) 1997 American Vacuum Society.
