Journal ArticleDOI
Band gap engineering based on MgxZn1−xO and CdyZn1−yO ternary alloy films
Takahiro Makino,Y. Segawa,Masashi Kawasaki,Akira Ohtomo,R. Shiroki,K. Tamura,Tadashi Yasuda,Hideomi Koinuma +7 more
TL;DR: In this paper, the structural and optical properties of II-VI oxide alloys, MgxZn1−xO and CdyZn 1−yO, grown by pulsed-laser deposition, were described.
Journal ArticleDOI
Single crystalline ZnO films grown on lattice-matched ScAlMgO4(0001) substrates
Akira Ohtomo,K. Tamura,K. Saikusa,Kunio Takahashi,Takahiro Makino,Y. Segawa,Hideomi Koinuma,Masashi Kawasaki +7 more
TL;DR: In this paper, lattice-matched (Δa/a=0.09%) ScAlMgO4(0001) substrates were employed to grow single crystalline quality ZnO films by laser molecular-beam epitaxy.
Journal ArticleDOI
Negative-U System of Carbon Vacancy in 4H-SiC
Nguyen Tien Son,Xuan Thang Trinh,Lars Løvlie,Bengt Gunnar Svensson,Koutarou Kawahara,Jun Suda,Tsunenobu Kimoto,Takahide Umeda,Junichi Isoya,Takahiro Makino,Takeshi Ohshima,Erik Janzén +11 more
TL;DR: Using EPR and deep-level transient spectroscopy, it is shown that the two most common defects in as-grown 4H-SiC--the Z(1/2) lifetime-limiting defect and the EH(7) deep defect--are related to the double acceptor and single donor levels of V(C), respectively.
Journal ArticleDOI
Gallium concentration dependence of room-temperature near-band-edge luminescence in n-type ZnO:Ga
Takahiro Makino,Y. Segawa,Shin'ichirou Yoshida,Atsushi Tsukazaki,Akira Ohtomo,Masashi Kawasaki +5 more
TL;DR: In this paper, the optical properties of epitaxial n-type ZnO films grown on lattice-matched ScAlMgO4 substrates were investigated and it was shown that the absorption edge showed a systematic blueshift, consistent with the Burstein-Moss effect.
Journal ArticleDOI
Optimization of zinc oxide thin film for surface acoustic wave filters by radio frequency sputtering
TL;DR: In this article, the authors investigated the interface microstructure of ZnO thin films by cross-section transmission electron spectroscopy and found that the average crystal size of the ZnOs on glass is larger than that of ZnsO on Al.
