Preparation of nanometer sized Mn doped Zn based oxides powder for DMS applications

Abstract

In order to study the size dependent DMS (Diluted Magnetic Semiconductor) behavior of Mn doped ZnO, the authors have systematically prepared a series of nanosized green powder based on Mn doped ZnO (Zn 1-x Mn x O, where x=0.02 - 0.1) materials using our novel and low cost pyrophoric reaction technique route. Microstructural (TEM) analysis of the green powder were carried out to understand the surface morphology, particle size and crystalline behavior (if any) of the green powders. It is observed that average particle size down to 20nm were formed by the Pyrophoric Reaction Technique Route which are the potential entity for the formation of high denisty nanostructured sintered ceramic target for preparation of ultra thin films of Zn based Diluted Magnetic Semiconductors (DMS)
