摘要：

Experiments reveal that the near surface second-order nonlinear optical susceptibility, chi(2)(2omega,omega,omega), is significantly affected by band-bending induced-electric fields in the depletion region of GaAs(001). Both n- and p-type GaAs samples exhibit a reduction of the bulk second-order susceptibility chi(yxz)(2) independent of electric field direction. A three band theoretical model was used to qualitatively explain these observations.
