| Abstract | A novel molecule template assisted chemical co-reduction method has been successfully developed for the controlled synthesis of ultrathin β-SiC single-crystalline nanowires on a large scale. The ultrathin β-SiC single-crystalline nanowires are about 8 nm in diameter and 200–800 nm in length. The resulting thin β-SiC single-crystalline nanowire is new in the family of β-SiC one-dimensional (1D) nanostructures. A synergistic action of π-stacking and steric hindrance result from the 1,10-phenanthroline molecule template are proposed to explain the growth mechanism of the ultrathin β-SiC single-crystalline nanowires based on the experimental observation. Importantly, such ultrathin β-SiC nanowire has shown a strong structure-induced enhancement of photoluminescence properties and has exhibited a very strong green light emission, which can be seen by naked eye. Furthermore, the unique β-SiC ultrathin nanowire structure exhibits a low turn-on field $(3.57 V μm^{−1})$ and a large field-emission current density $(20 mA cm^{−2}).$ These results suggest that the ultrathin β-SiC nanowires can be expected to find promising applications as field emitters and photoelectronic devices. |

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.
