摘要：

A series of subpicosecond time-resolved reflectivity measurements on n-type GaAs (100) interfaces at photoexcitation densities of 10(18) cm-3 is reported. It is observed that the temporal dependence of the reflectivity signal within the first several picoseconds following photoexcitation is highly dependent upon interface preparation. The surface of the GaAs was prepared in several ways: by the growth of a thermal oxide overlayer, a photochemically passivated oxide overlayer, and an epitaxial ZnSe overlayer.
