We fabricated and characterized the material with Mn (10 at.%: atomic percent) doped In3Sb1Te2 (MIST) using co-sputtering and synchrotron radiation, respectively. The MIST thin film showed phase-changes at 97 and 320 °C, with sheet resistances of ~10 kΩ(sq) (amorphous), ~0.2 kΩ(sq) (first phase-change), and ~10 Ω(sq) (second phase-change). MIST did not exhibit any chemical separation or increas...

Recent efforts on doping ZnO films for charge and spin functionality are reviewed, focusing on chemical doping for charge and spin device formation. Discussion includes the behavior of phosphorus as an acceptor and magnetism in transition metal-doped ZnO. Evidence for p-type behavior in phosphorus-doped (Zn,Mg)O grown by pulsed laser deposition is presented. The magnetic properties of ZnO co-do...

zno and mn-zno nano powders were prepared by the sol-gel auto combustion method. the products were characterized by x-ray diffraction (xrd), energy dispersive analysis of x-ray (edx) and scanning electron microscopy (sem). structural and morphological properties of nano particles were investigated and the average crystalline size of zno and mn-doped zno was obtained 44 and 51 nm, respectively. ...

The charge state and local ordering of Mn doped into a pulsed laser deposited single-phase thin film of ZnO are investigated by using x-ray absorption spectroscopy at the O K-edge, Mn K-edge and L-edge, and x-ray emission spectroscopy at the O K-edge and Mn L-edge. This film is ferromagnetic at room temperature. EXAFS measurement shows that Mn(2+) replaces the Zn site in tetrahedral symmetry, a...

Three kinds of silicate phosphor thin films, emitting in the red-green-blue (RGB) primary colors, were fabricated by pulsed laser deposition: manganese and lead doped calcium silicate (CaSiO3:MnPb) for red color, manganese doped zinc silicate (Zn2SiO4:Mn) for green color, and cerium doped yttrium silicate (Y2SiO5:Ce) for blue color. A good correlation was found between photoluminescence intensi...
