The present book deals with the phenomena of opto-electronic and elastic properties of binary (II-VI and III-V) semiconductors having tetrahedral structure. The binary semiconductors taken for study belong to Zinc-blende and Wurtzite structure. In the present book we have developed a simple model based on plasma oscillations theory of solids, which require minimum knowledge of the semiconductors to investigate opto-electronic and elastic properties. The physical concept taken for this purpose is that the plasmon energy is directly or indirectly related with many opto-electronic and elastic...
