鉬陰極 的英文怎麼說
中文拼音 [mùyīnjí]
鉬陰極
英文
molybdenum cathode-
So re oxides has two form existence, one is concentrate on the matrix equiaxial crystal grain boundary as a micron particles and the other is distributed in matrix crystal dispersively as the nanometer particles compared the electron emission performance of mo - la2o3, mo - ; la2o3 - y2o3 and mo - la2c > 3 - sc2o3 cathode, the mo - la2o3 - sc2c > 3 cathode show excellent electron emission character
上述研究表明不論是在稀土?鉬陰極還是在稀土?鎢電極中，稀土氧化物的存在形式有兩種，一種是微米級的顆粒偏聚于晶界處，另外一種是彌散分佈於基體晶粒的納米小顆粒。The research focus concentrates on the use of feas as a cold cathode source for microwave power amplifiers or flat panel displays. now silicon and molybdenum are the most popular materials used for tip field emitter arrays
針對目前場發射陣列陰極的研究情況，較為常用的是鉬微尖場發射陣列和硅微尖場發射陣列。However, both of them have disadvantages. mo tip feas is fabricated by evaporating tip cathodes on base, so it has bad coherence with the base. on the other hand, the characteristics of silicon result in the bad heat stability, bad emission reliability, and low current density
然而，這兩種陰極存在各自的缺點，如鉬尖錐是蒸鍍在基底上的，所以與基底的附著力不強;而硅的特性又決定了其熱穩定性差，發射的可靠性低，發射電流有限。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。This research has studied the microstructure of cathode materials systematically by the means of high resolution transmission electron microscopy and scanning electron microscopy, surveyed the electron emission performance of la2o3, - mo, la2o3 - y2o3 - mo, la2o3 - sc2c > 3 - mo cathode with the self - designed electron emission surveyor and analyzed the elements changing of the surface of mo - la2o3 - sc2c > 3 cathode in - situ. while it was heated to different temperature. at last, the relationship of the microstructure of cathode, diffusion of active matter and electron emission performances has been discussed
本研究採用高分辨掃描電鏡、透射電鏡對稀土鉬鎢陰極材料的顯微結構進行了系統研究；利用本課題研究組設計研製的電子發射測量儀對la2o3 - mo ， la2o3 - sc2o3 - mo ， la2o3 ? y2o3 - mo三種陰極（以下稱鑭?鉬陰極、鑭鈧?鉬陰極、鑭釔?鉬陰極）的發射性能進行了測量；利用經改造后的俄歇電子能譜儀「原位」分析了發射性能較好的鑭鈧鉬陰極在不同溫度下表面活性元素的變化情況。Experimental research for the specific property of mo poly - crystal cathode
金屬鉬陰極發射特性的實驗研究Through this device, la - mo cathode was deposed and analyzed without exposed to the atmosphere
