摘要
The emission spectra from sulfurized p-InP annealed at temperatures below 300°C are compared with those from untreated samples annealed under the same conditions. The unsulfurized samples show a VP related emission band at 1.14 eV whose intensity increases linearly with annealing temperature. The sulfurized samples exhibit an emission band at 0.94 eV attributed to a S P deep level. Both bands disappear when a layer of 20 Å is chemically removed. This shows that both VP and SP formation is limited to a few atomic surface layers.
