Solid State Engineering Physics - 2ED

The development of many advanced technologies has made life easier. To apply the materials in any field we should aware of the internal structure of the materials. Crystal structure deals with the repetitive atomic arrangement and a related fundamental of it is described in Chapter-I.Chapter-II is about Quantum physics which completely revolutionized the realization or the thought processes related to every phenomenon especially in the atomic scale. As we all now expect the twenty first century as the century of nanomaterials we should have a complete understanding of quantum physics as a building block.The valence shell electrons of metals are responsible for overall behaviour of metal. Modification in the previous theory have been made by applying quantum mechanics and are discussed in Chapter-III.The understanding of semiconductor materials requires different approach other than metals and is discussed in Chapter-IV. The electrons in solid crystalline materials are under the influence of a periodic electric field produced by regularly placed ions at their lattice sites of the crystal.The popularity of photosensors arises due to their compactness low cost simple operational procedures high sensitivity high response speed minimum noise and outstanding reliability besides other advantages. These are discussed in Chapter-V.The control of microstructure for obtaining the desired magnetic properties is today almost as important as the control necessary for achieving their optimum mechanical properties. The magnetic materials make considerable change in magnetic field by magnetization and they are described in Chapter-VI.Superconductors are presently materials of high interest. In Chapter-VII the zero resistivity along with perfect diamagnetic property of them are discussed in details.Nanotechnology is the interdisciplinary technology of the 21st century and it will clearly decide the fate of our civilization in future. Explosive growth is currently taking place in this field. In Chapter-VIII we have introduced nanotechnology by explaining the basics of it with historical developments. In Chapter-IX different sophisticated tools required for the characterization in and beyond nanoscale e.g. electron microscopes and spectroscopic instruments are explained with suitable diagrams.
