The prepared diamond layers on tungsten wires showed such electron field emission properties.

The status of thin-film silicon cell technology is reviewed by comparing it to other major solar cell technologies. The basic operation principles and the shortcomings of a-Si:H solar cells are outlined. The multi-junction and multi-band gap approach for obtaining highly efficient a-Si:H based solar cells is introduced. Application of novel materials, such as hydrogenated microcrystalline silicon and protocrystalline silicon, and efficient light trapping techniques in the multi-junction solar structures is highlighted. A novel temporary superstrate concept for a low-cost roll-to-roll production of thin-film silicon solar cells that has been developed in the Netherlands is presented.","PeriodicalId":179900,"journal":{"name":"The Fourth International Conference on Advanced Semiconductor Devices and Microsystem","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2002-12-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127573946","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The small lead-to-lead separation results increased crosstalk effects inside the integrated circuits. A method was designed to facilitate the forecast of crosstalks in integrated circuits using simple passive LCR circuit models of connecting lines. It appears possible, given a well defined standard interconnecting technology, to forecast the maximum value of crosstalk in a digital system regardless of the physical length of the mutually interfering leads. This presents a major design advantage since the maximum crossialk value can be determined using simple equations without any need to pe form circuit simulations of digital systems including the influence of parasitic couplings. The application of these limit cases can speed up considerably the design of electromagnetically compatible electronic systems.","PeriodicalId":179900,"journal":{"name":"The Fourth International Conference on Advanced Semiconductor Devices and Microsystem","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2002-12-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125305719","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
