Structure and magnetic properties of Mn-doped ZnO thin films
We report the structure and magnetic properties of Zn1–xMnxO thin fi lms grown on Si(001) substrates by pulsed laser deposition. Structure and phase evolution with Mn doping has been studied using x-ray diffraction, electron diffraction, and high-resolution electron microscopy. The undoped and 1% Mn-doped ZnO fi lms are completely (001) oriented, and further Mn doping deteriorates the (001) ori...
متن کاملCorrelation between crystal structure and optical properties of copper- doped ZnO thin films
ZnO and Cu doped[1] (CZO) thin films were prepared by radio frequency sputtering. The structural and optical properties of thin films were investigated using X-ray diffraction (XRD), atomic force microscopy (AFM), optical spectrophotometer, and photoluminescence (PL) techniques. ZnO thin films showed crystalline and micro-stress defects in the crystal lattice. Annealing of CZO thin films increa...

15 صفحه اولSynthesis and magnetic properties of Mn doped ZnO nanowires
Mn doped ZnO nanowires have been synthesized using a simple autocombustion method. The as-synthesized Mn doped ZnO nanowires were characterized by X-ray diffraction and transmission electron microscopy. An increase in the hexagonal lattice parameters of ZnO is observed on increasing the Mn concentration. Optical absorption studies show an increment in the band gap with increasing Mn content, an...
متن کاملEpitaxial Mn-doped ZnO diluted magnetic semiconductor thin films grown by plasma-assisted molecular-beam epitaxy
A growthwindow for theMn effusion cell temperature (TMn) is demonstrated for epitaxialMn-doped ZnO (MnZnO) thin films grown on sapphire substrates using molecular-beam epitaxy. Within the growth window, the films are ferromagnetic with the largest saturated magnetization occurring at TMn1⁄4700 1C. The Curie temperature of these MnZnO diluted magnetic semiconductor thin films is above roomtemper...
