Control of dot sizes and spatial distributions may be improved by templated growth. Instead of an array of nanoparticles, it is also possible to use single quantum dots, and exploit Coulomb blockade and multi-level storage in single electron/few electron charge memories, but such devices are susceptible to background charges. It is possible to envision vertical cell structures in a cross-point array at the intersections of the wordlines and bitlines, which can result in an ideal 4F/sup 2/ architecture.","PeriodicalId":385948,"journal":{"name":"Conference Digest [Includes 'Late News Papers' volume] Device Research Conference, 2004. 62nd DRC.","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2004-06-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128665258","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 following outcomes of our simulations are noteworthy: i) partially due to the relatively heavy electron effective mass in GaN, the velocities of the electrons are mostly below the steady state values through most of the channel; ii) unlike what is observed in GaAs based short channel devices, there is no pronounced overshoot effect, even at high drain source biases, due to increased scattering; iii) our simulations show that the suppression of overshoot is directly related to the length of the high field region. This length is quite small for usual bias conditions. We suggest that a non-uniform composition of the barrier region could conceivably help in spreading out the high field region, which is present at the drain end of the device. Other results of the Monte Carlo simulation include transconductance, noise information and unity current gain frequency.","PeriodicalId":385948,"journal":{"name":"Conference Digest [Includes 'Late News Papers' volume] Device Research Conference, 2004. 62nd DRC.","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2004-06-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127769337","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}

Currently ohmic contact technology requires a high temperature (/spl sim/870/spl deg/C) alloying step. The resulting contacts have an irregular shape and surface that can create difficulties in device reproducibility, reliability and yield, particularly for large periphery devices. The use of ion implantation to enable unalloyed ohmic contacts has the potential to reduce these obstacles to the manufacturability of AlGaN/GaN HEMTs. Using ion implantation also has the potential to reduce access resistance by reducing ohmic contact resistance and gate-source spacing, to eliminate the need for etched device isolation, and to enable sophisticated device designs that take advantage of lateral dopant engineering.","PeriodicalId":385948,"journal":{"name":"Conference Digest [Includes 'Late News Papers' volume] Device Research Conference, 2004. 62nd DRC.","volume":"123 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2004-06-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126336036","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}
