| Abstract | The distinction between hard and soft materials is most frequently described at the microscopic level as a difference in the nature of the bonding and molecular assembly, but concepts of “soft” and “hard” are more intuitively associated with macroscopic mechanical properties, such as stiffness or hardness. The behavior of a hard material may resemble that of a soft material in many aspects when a structural dimension is reduced to the nanoscale, even if elastic constants and moduli do not change. When semiconductor crystals, strongly covalently bonded and brittle, are made into membranes as thin as a few nanometres, they can behave like traditional soft matter, while maintaining their single-crystal structure without defects even after substantial deformation. This review presents single-crystal Si in a new fashion, i.e., as a form of soft matter, if fabricated as flexible nanomembranes, and suggests a plethora of interesting science and many applications that may benefit from the use of Si in this “soft matter” form. We suggest that the nanomembrane form gives Si an additional, new life as a soft material. |

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.
