【摘要】 低能电子衍射仪(LEED)是研究单晶表面结构的有效工具。本文叙述我们研制LEED仪的一些要求、实现方法和达到的指标。为检验LEED仪的性能,我们观察了清洁Cu(100)面及氧吸附层的LEED图样,图样是清晰而满意的。更多还原

【Abstract】 LEED is an effective instrument for the study of surface structures of single-crystals. The paper describes the requirements of the instrument made by ourselves. In order to examin the instrument, we have observed the LEED patterns of clean surface and oxygen-adsorbed surface of Cu (100), the patterns are sharp and satisfactory.更多还原
