Semiconductors are those compounds with small band gaps between fully filled and fully unoccupied bands.Let us consider the elements of Group 14. These all adopt the structure of diamond, in which the atoms are all tetrahedrally coordinated by other atoms. Band Structure in Body Centered Cubic crystal Band Structure in tetrahedral diamond crystal If the Group 14 elements adopted a typical metal structure, such as the body centered cubic structure, the ns- and np-orbitals would overlap to give an extended band of s/p chara

Metals have structures which may be discussed in terms of the close packing of spheres, and as a result have the high coordination numbers of the close packed systems. Ionic solids, however, have lower coordination numbers, and the discussion of the structure simply in terms of close packed species has to be adapted.The idea of an ionic solid, though, depends on being able to define an ion. The Ionic Model treats a solid as being made up of oppositely charged spheres that interact by the coulombic forces between them, and the short range repulsive forces which occur between closed shell species at small separations.The use of the idea

NEW DELHI: The government's plan to introduce the common entrance test (CET) for engineering from 2013 hit a roadblock on Wednesday, with the faculty representatives of the Indian Institutes of Technology (IITs) asking for the proposal to be put on hold till there are further discussions. When asked about the meeting, HRD ministerKapil Sibal only said that it went off well. The minister and senior HRD officials met with IIT directors and chairpersons and representatives of the All India IIT Faculty Federation (AIIFF) on Wednesday for the first time after the tech institutes expressed concerns about the new system that is expected

Engineers belong to the greatest profession in the world, responsible for almost everything that makes life worth living - from leisure activities to medical treatment, mobile communications to modern transport systems.Within the wide boundaries of the engineering profession, there are thousands of challenging activities, in areas such as research, development, design, manufacture and operation of products and services. Activities which provide stimulating intellectual challenges with diverse and varied tasks, inevitably involving deadlines, and all added to the satisfaction of real output or delivery.Demand for good engineers is high, in practically every country i

The IIT K director recently disclosed that the new entrance system will give 50% weightage to the new entrance test score( essentially, a test which will be JEE+aptitud equestions+GK(?)) and 50% weightage to the board percentiles. However, a lot of you might be confused as to how it will workAs CBSE is the most popular board around, I ll analyse the impact of the new scheme on CBSE aspirants.Analysing percentile vs percentage charts from a recently conducted CBSE exam(http://www.docstoc.com/docs/36701910/CBSE-Percentile), we get the following conversions(rounded off):97.xx % = 100 percentile = 50/5095% = 97.2 percentile = 48
