Electronic structure and transport properties of Cu-deficient kuramite Cu3-xSnS4
Yosuke Goto, Yuki Sakai, Yoichi Kamihara +1
Electrical and thermal transport properties of Cu-deficient kuramite Cu3-xSnS4 (CTS) was examined as a possible earth-abundant thermoelectric material. Crystallographic structure o…
Pulsed Low-Field Electrically Detected Magnetic Resonance
L. Dreher, F. Hoehne, H. Morishita +4
We present pulsed electrically detected magnetic resonance (EDMR) measurements at low magnetic fields using posphorus-doped silicon with natural isotope composition as a model syst…
Enhancement of thermoelectric properties by Se substitution in layered bismuth-chalcogenide LaOBiS2-xSex
Yoshikazu Mizuguchi, Atsushi Omachi, Yosuke Goto +5
We have investigated the thermoelectric properties of the novel layered bismuth chalcogenides LaOBiS2-xSex. The partial substitution of S by Se produced the enhancement of electric…
Host isotope mass effects on the hyperfine interaction of group-V donors in silicon
T. Sekiguchi, A. M. Tyryshkin, S. Tojo +12
The effects of host isotope mass on the hyperfine interaction of group-V donors in silicon are revealed by pulsed electron nuclear double resonance (ENDOR) spectroscopy of isotopic…
Effects of the Cu off-stoichiometry on transport properties of wide gap p-type semiconductor, layered oxysulfide LaCuSO
Yosuke Goto, Mai Tanaki, Yuki Okusa +4
Layered oxysulfide LaCuSO (x = 0-0.03) was prepared to elucidate the effect of Cu off-stoichiometry on their electrical and thermal transport properties. Electrical resistivity dra…
Spin-dependent recombination at arsenic donors in ion-implanted silicon
David P. Franke, Manabu Ostuka, Takashi Matsuoka +4
Spin-dependent transport processes in thin near-surface doping regions created by low energy ion implantation of arsenic in silicon are detected by two methods, spin-dependent reco…
