孟 显 %A 王友年 %J 物理学报 %D 1998 %I %X The wake potential and energy loss of a swift ion moving parallel to a heavily doped semiconductor surface in vacuum are studied with the specular-reflection model and the dielectric response theory. The phonon-electron coupling effect on the surface wake potential and the energy loss is investigated by using a frequency-dependent dielectric function. We find that there are two branches of phonon-electron coupling excitations which contribute to the wake potential and the energy loss. Numerical results show that the oscillation form of the wake potential is obviously influenced by the phonon-electron coupling effect. %K 半导体 %K 声子电子效应 %K 离子杂杂 %K 表面感应电势 %U http://www.alljournals.cn/get_abstract_url.aspx?pcid=6E709DC38FA1D09A4B578DD0906875B5B44D4D294832BB8E&cid=47EA7CFDDEBB28E0&jid=29DF2CB55EF687E7EFA80DFD4B978260&aid=478BD5F0F36565A6EFA7C6F6C928A33C&yid=8CAA3A429E3EA654&vid=F4B561950EE1D31A&iid=DF92D298D3FF1E6E&sid=EF10DC5E94EFF05A&eid=7C112B12217D9FAF&journal_id=1000-3290&journal_name=物理学报&referenced_num=0&reference_num=3
