| Abstract | An integrated thermal-mechanical simulation of buckling in nano-mechanical memory is performed. The preliminary system is a bridge with a length of 20 microns, a width of 1 micron, and a thickness of 300 nm, in air with a pressure of 5 kPa. Conduction along the bridge as well as convection between the beam and the gas are considered. Simulations are performed for silicon with different dimensions. Longer structures will buckle faster at less temperature and will require less energy to actuate. However, the ideal array would use the smallest beams possible. The current work suggests the length of 20 microns for the unit of the bridge to balance these constraints. As the thickness of the bridge increases, the energy consumption increases due to an increase of moment of inertia. The buckling time increases by increasing the thickness while it decreases by increasing the width. The study of high particle energy collision shows these particles do not cause fast undesired buckling. The heat through collision dissipates in less than 10 nsec which is much smaller than the smallest buckling time. |

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.
