However, the most commonly used x - ray sources didn " t change much no matter in structure or theory, still using thermionic cathodes as electron sources. such conventional x - ray tubes have some defaults, such as big volume, low frequency response, demanding for supply to cathode that was also brittle
目前使用的x光源的基本特點是採用熱電子發射形式即採用熱燈絲作為電子發射源,在高壓加速下轟擊陽極產生x射線,這樣的光源體積較大,需要加熱陰極的電源,且對頻率響應慢。When these organic materials meet each other they may form exciplex which introduce new spectral lines and reduce original ones. we compared the spectra of samples ito / tvk : tpb / alg3 / al and ito / pvk : tpb / mgf / alg3 / al. we found that the spectrum from exciplex is much reduced
有機材料的載流子遷移率低,不可能實現碰撞離化,它的發光只能是和陰極射線管中的發光一樣,來源於從sioz加速出來的電子對有機材料的直接碰撞。In this paper , first, the author drew some important conclusions by analyzing several technical factors and experimental conditions which would have great influence on the quality of diamond thin films during mpcvd process , including gas proportion , the power of microwave , the plasma ' s location, the nucleation technique, etc. finally , the author has successfully deposited nanocrystalline diamond thin films with 300nm crystal particles on the slick surface of silicon by using ch4 / h2 gases in the mpcvd system , and the nanocrystalline diamond thin films was proved to have good field emission performance. all these researches will make the foundation for the field emission cathode of diamond films
本論文中,作者分析了mpcvd方法中氣源成分比、微波功率、等離子體球的位置、成核技術等各種工藝條件對金剛石薄膜質量的影響,並總結得到了一些有意義的結論;同時,在自行研製的mpcvd沉積系統上,於4 - 7kpa 、 1000左右的熱力學條件下,採用ch4 / h2氣源氣氛在光滑的硅襯底上制備出了晶粒尺寸在300納米以下的納米晶金剛石薄膜,測試得到了較好的薄膜場致電子發射性能,為金剛石薄膜場致發射冷陰極的研究工作打下了實驗基礎。Carrier aggregation on the interface between organic layer and electrodes may screen extra electric field and reduce barrier height for carrier injection. ( 3 ) we utilized oxd as buffer layer in anode and lif in cathode in single layer mehppv pleds. and the efficiency and brightness was doubled. the results implied that aggregation of minority carriers at the interface may the role of blocking layer
( 3 )在單層mehppv器件的陽極引入oxd作為電子阻擋修飾層, lif作為陰極修飾層,利用阻擋少數載流子實現界面電荷積累的方法提高了器件發光亮度和效率,分析了器件電流電壓特性,使器件發光效率和亮度提高了一倍以上。Using field emission cathode, x ray source can be made with several advantages : smaller volume and brighter, high frequency response, in - time turning on, etc. considering of the merits and potential markets, researching and fabricating miniature x - ray source is meaningful
由於突起數目大且尖端頂端電場強度高,因此產生很大的場發射電流密度。採用場發射陰極的x射線光源具有體積小,輻射強度高,頻率響應快,可以隨時開啟,無需預熱的優點。分享友人
