Abstract
The symmetry properties of surface second-harmonic generation (SHG) have been studied for compound semiconductor materials, such as GaAs, in which the nonlinear susceptibility of the bulk does not vanish. The rotation-angle dependence (anisotropy) of the intensity of surface-reflection SHG for singular as well as vicinal surfaces, with and without surface tensor components, was examined and compared with the existing experimental results.Keywords
