摘要：
A study of the Sb{single bond}GaAs(110) system, over a wide range of coverage, by means of High Resolution Electron Energy Loss Spectroscopy is presented. A structure related to an electronic transition proper of antimony is shown and interpreted. The influence of Sb on the Fuchs-Kliewer phonon as well as on the free carrier plasmon of n-doped GaAs is shown and related to screening properties of the overlayer, in correspondance to a critical coverage of about 15 monolayers. © 1990 Pergamon Press plc.
