Item type:Item, Spatial distributions of elastically backscattered electrons from copper and silver(1999-12-21) ;Kwei, CM ;Hung, CJ ;Su, P ;Tung, CJ電子工程學系及電子研究所We investigated the spatial distributions regarding the pathlength, the penetration depth, and the lateral displacement of 200-2000 eV electrons elastically backscattered from copper and silver We calculated these distributions by the Monte Carlo method using elastic scattering cross sections and inelastic inverse mean free paths for volume and surface excitations. in our approach, we applied the partial wave expansion method and the finite difference technique to calculate electron elastic cross sections by the Hartree-Fock-Winger-Seitz scattering potential for solid atoms. We employed the extended Drude dielectric function to estimate electron inelastic mean free paths inside the solid and electron surface excitation parameters outside the solid. Our study was focused on the energy dependence of the pathlength distribution, the maximum depth distribution and the radial distribution. We found that both the radial displacement and the maximum depth of backscattered electrons were on the order of a few angstroms. The maximum depth and the pathlength distributions obeyed the exponential attenuation form. The ratio of the attenuation lengths for the pathlength and the maximum depth distributions saturated to a value somewhat greater than two. Considering the back and forth trajectories of backscattered electrons, it revealed that mast electrons were backscattered from the solid through a single elastic scattering or a few elastic scatterings. As electron energy decreases, this ratio became larger, indicating that the probability for smaller scattering angles increases.Item type:Item, 月亮兇手(1999-12-25)管管Item type:Item, ZnO變阻陶瓷毫米波燒結技術研究(III)(2000) ;郭正次 ;KUO CHENG-TZU國立交通大學材料科學與工程學系Item type:Item, 澳洲論述:文學與電影(II)(2000) ;蔣淑貞 ;CHIANG SHU-CHEN國立交通大學外文系Item type:Item, 切削動態及路徑追蹤之交互作用及對工件輪廓之影響(2000) ;秦繼華 ;CHIN JIH-HUA國立交通大學機械工程學系Item type:Item, 應用於深次微米CMOS元件之閘極氧化層與複晶矽介電層之技術開發(2000) ;雷添福 ;LEI TAN-FU交通大學電子工程系Item type:Item, 網格動態系統的型及混沌現象(I)(2000) ;林松山 ;LIN SONG-SUN國立交通大學應用數學系Item type:Item, 極軟弱岩石之大地工程行為(I)---子計畫一:深基礎在軟弱岩石中之行為(2000) ;黃安斌 ;HUANG AN-BIN國立交通大學土木工程學系Item type:Item, 網路合作設計科學活動之環境、學習、與評估---子計畫III:網路合作設計環境及社群設計科學活動的知識建構之評估(II)(2000) ;林珊如 ;LIN SUNNY S.J.交通大學教育學程中心Item type:Item, IC製造業學習曲線之應用研究(2000) ;楊金福交通大學工業工程與管理系Item type:Item, 利用電荷幫浦分佈法研究深次微米N型MOS元件電漿製程傷害之可靠性(2000) ;莊紹勳 ;Chung Steve S國立交通大學電子工程研究所Item type:Item, 新型光電材料與光子晶體之光電物理性質研究(2000) ;謝文峰 ;HSIEH WEN-FENG交通大學光電工程研究所Item type:Item, CMOS發光顯像技術與閘極介電層材料研究---中加合作案(I)(2000) ;汪大暉 ;WANG TAHUI國立交通大學電子工程學系Item type:Item, 具有新式副閘極結構的低溫複晶矽薄膜電晶體的製作與分析(2000) ;黃調元 ;TIAO-YUANHUANG國立交通大學電子工程學系Item type:Item, 薄膜型微波通訊被動元件之設計與製作---子計畫三:鑽石與低介電類鑽薄膜在薄膜型微波通訊元件之應用研究(2000) ;陳家富 ;CHEN CHIA-FU國立交通大學材料科學與工程學系Item type:Item, 最後的達賴喇嘛(時報, 2000)林照真Item type:Item, 高分子黏彈性的普偏性的研究(II)(2000) ;林銀潢 ;LIN YN-HWANG交通大學應用化學系Item type:Item, Indonesian political transition, democracy and women's movements: experience and reflections(Routledge, 2000)C.
