| Abstract: | ![]()
A nonmonotonic behavior of band bending φ S as a function of cesium coverage ? on the Cs/GaAs(001) surface is observed in the form of several maxima and minima. This behavior indicates the formation of the quasi-discrete spectrum of the adatom-induced electronic surface states. The hysteresis of the φ S (?) dependence under adsorption and subsequent thermodesorption of cesium indicates the metastability of the Cs/GaAs(001) system. |
