Investigations on pure and doped tio2 And zno thin films and the effect of Swift heavy ion irradiation on Mn doped zno thin films

Abstract

Diluted magnetic semiconductors DMS are referred as semimagnetic semiconductors with lattice partly substituted by magnetic atoms In order to develop new electronics it is essential to combine both charge and spin of the electrons In this the spin of electrons that carries the information can be used as an added degree of freedom in novel electronic devices Thus the emerging research area known as spintronics or spin based electronics seeks to extend the properties and applications of established devices by making use of the spin of electrons in addition to their charge newline Oxides based DMS have been reported to be robust room temperature ferromagnets Generally oxide semiconductors have many advantages like wide bandgap transparency and dyeability with pigments high n type carrier concentration capability to be grown at low temperature even on plastic substrate ecological safety durability and low cost newline newline
