Abstract | The scaling characteristics of both n- and p-channel Ge-on-insulator (GOI) as well as silicon-on-insulator (SOI) MOSFETs with channel length ranging from 20-130 nm are studied by a two-dimensional self-consistent fullband Monte Carlo device simulator. The transistors' intrinsic performance and subthreshold characteristics are investigated for various channel lengths and Ge layer thicknesses. Our results indicate that both n- and p-channel GOI MOSFETs can be scaled down to the nanoregion, due to the nonstationary transport, especially for the p-channel device. More than 10% performance improvement for nMOS and about 20% for pMOS can be achieved in GOI even when channel length is scaled down to 20 nm, as compared to SOI devices. However, the GOI devices suffer from more severe short channel effect and have larger p-n junction leakage current as compared to SOI counterpart. For high-performance CMOS applications, GOI devices are feasible if the junction leakage can be reduced by optimizing the device structure. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
