ABSTRACT
Picosecond laser-induced melting and evaporation of GaAs surfaces are studied. The high reflectivities of molten GaAs observed at fluences above the melting threshold have a wavelength dependence inconsistent with a simple Drude model for a metallic molten GaAs surface. The observations at high laser fluences suggest that the liquid-vapor phase transition is initiated by a fast-expanding, high-density fluid.

    Gallium arsenide (GaAs) is one of the most important materials among the III-V family, especially in view of its applicability to optoelectronic devices. However, it is known that GaAs, unlike silicon (Si), does not possess a stable native oxide that can passivate and protect the surface. This...
