| Abstract | Physical and technical characteristics and possibilities of express, nondestructive, compatible with the existent technologies, computerized setup for ex-situ second harmonic generation diagnostics of crystal quality of semiconductor and dielectric plates and films without the center of symmetry (GaAs, CdTe, SBN) are presented. Brief characteristics of similar laboratory installation for in-situ express second harmonic generation diagnostics of semiconductor films crystal quality are given. The "ex-situ" setup is able to define the axes orientation with the accuracy about 0,1 degree by the analysis of the SH intensity dependence versus laser light polarization rotation with the space resolution up to 40 microns, operation time about 1 minute. It produces simultaneously the map of surface layer crystal quality distributions and the map of volume crystal and optical quality distributions. By this operation the thickness of studied surface layer 0,1-1 micron, the size of scanned area from 0,5/sup */0,5 mm/sup 2/ up to 60/sup */60 mm/sup 2/, number of map elements 100/sup */100, space resolution up to 40 microns, time of maps generation about 15 minutes. The demonstrated possibilities of SH testing of GaAs, CdTe, SBN quality give a chance to have convenient, express and technological tool for the laboratory and factory output inspection. |

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.
