摘要：

We present theoretical studies of the optical anisotropy spectra of GaAs(001) surfaces with different reconstructions at growth temperatures. The Ga-rich (4 X 2) missing-dimer surface, three different phases (alpha, beta, and gamma) of the As-rich (2 X 4) surface, and an As-rich c(4 X 4) surface are considered. Total energy calculations within a nearest-neighbor tight-binding model are performed to determine the surface geometry for each reconstruction considered. The difference between reflectance spectra with [110] and [110BAR] polarization for these surfaces is analyzed and compared to available data.
