MgxZn1−xO as a II–VI widegap semiconductor alloy
Akira Ohtomo,Megumi Kawasaki,Takashi Koida,K. Masubuchi,Hideomi Koinuma,Y. Sakurai,Yasuhiko Yoshida,Tadashi Yasuda,Yusaburo Segawa +8 more
TL;DR: In this article, a wide gap II-VI semiconductor alloy, MgxZn1−xO, was proposed for the fabrication of heteroepitaxial ultraviolet light emitting devices based on ZnO.
Journal ArticleDOI
High throughput fabrication of transition-metal-doped epitaxial ZnO thin films: A series of oxide-diluted magnetic semiconductors and their properties
Zhengwu Jin,Tomoteru Fukumura,Megumi Kawasaki,K. Ando,Hidekazu Saito,Takashi Sekiguchi,Y.-Z. Yoo,Makoto Murakami,Yuji Matsumoto,T. Hasegawa,Hideomi Koinuma +10 more
TL;DR: Combinatorial laser molecular-beam epitaxy method was employed to fabricate epitaxial ZnO thin films doped with all the 3d transition metal (TM) ions in a high throughput fashion as discussed by the authors.
Journal ArticleDOI
Metallic ordered double-perovskite Sr2CrReO6 with maximal Curie temperature of 635 K
Hiromitsu Kato,Tetsuji Okuda,Yoichi Okimoto,Y. Tomioka,Y. Takenoya,A. Ohkubo,Megumi Kawasaki,Y. Tokura +7 more
TL;DR: A 2CrReO6 (A=Sr and Ca) was found to be a metallic ferromagnet with a high Curie temperature (TC=635 K), possibly the highest-TC half metal among the perovskite family as mentioned in this paper.
Journal ArticleDOI
Room-temperature stimulated emission of excitons in ZnO/(Mg, Zn)O superlattices
Akira Ohtomo,K. Tamura,Megumi Kawasaki,Takayuki Makino,Yusaburo Segawa,Zikang Tang,George K.L. Wong,Yuji Matsumoto,Hideomi Koinuma +8 more
TL;DR: In this paper, the authors reported on the observation of stimulated emission in ZnO/MgxZn1−xO superlattices well above room temperature.
Journal ArticleDOI
Principles of superplasticity in ultrafine-grained materials
TL;DR: In this paper, the authors examined various reports of superplasticity in ultrafine-grained materials and showed that these materials exhibit many characteristics similar to conventional super-plastic alloys.
