A large number of attempt and painstaking experiment have been done in this paper according to existing project . we also do lots of chemical and electrochemical etching research in material of lab6 , and find out three kind of methods to produce the field emitting cold cathode including reactive ion etching ( rie ) with oxygen , wet process etching and electrochemical etching . through produce some field emitting cold cathode single tip including lab6 field emitting cold cathode , molybdenum field emitting cold cathode , tungsten field emitting cold cathode , tungsten rhenium field emitting cold cathode , molybdenum covered with lab6 film field emitting cold cathode 而且,目前可借鑒的參考文獻較少,圍繞著前人做過的方案,本文做了大量工作,在已有文獻介紹的基礎上,結合原有的理論和實踐基礎,摸索出了包括高溫氧作用反應離子( rie )刻蝕法、濕法腐蝕法和電化學腐蝕法在內的三種制備工藝,運用電化學腐蝕工藝成功制備了單尖的六硼化鑭場發射冷陰極尖錐、鉬場發射冷陰極尖錐、鎢場發射冷陰極尖錐、鎢錸合金場發射冷陰極尖錐以及有六硼化鑭薄膜覆蓋的鉬場發射冷陰極尖錐。
