The surface structure of (NH4)2S x -treated InAs (001) was studied by means of coaxial impact collision ion scattering spectroscopy (CAICISS) and low-energy electron diffraction (LEED). These observations revealed that arsenic atoms at the outermost surface are partially replaced by sulfur atoms. Significantly, the (2×1) reconstruction of the (NH4)2S x -treated surface with heat treatment at 380°C is described by the formation of dimers lined up in [11̄0] direction. This surface model is supported by the data obtained by synchrotron radiation photoemission spectroscopy (SRPES).
