A perspective on zinc oxide based diluted magnetic semiconductors

Abstract

Diluted magnetic semiconductor (DMS) is envisaged to portray a substantial position in inter-punitive material science and prospect spintronics. The reason being spin and charge degrees of freedom are accommodated into solitary matter and their interaction is anticipated to probe innovative electronic devices. DMSs evince multifarious advantages such as wide band gap apposite for applications with short wavelength light, transparency and dye ability with pigments, high carrier concentration, capability to be cultivated even on plastic substrate at low temperature, green safety, durability, most importantly economical. Various theoretical and experimental research findings have been proposed on the ferromagnetic, paramagnetic, antiferromagnetic and spin glass properties at room-temperature of transition metal-doped DMSs such as TiO2, ZnO, Cu2O, SnO2, In2O3 etc in last few years. The objective of the paper is to comprehend the recent research advancement of ZnO based DMS specimens doped with various 3d transition metals.
