Irradiation induced modification of the superconducting properties of heavily boron doped diamond
Daniel Creedon, Yi Jiang, Kumaravelu Ganesan +7
Diamond, a wide band-gap semiconductor, can be engineered to exhibit superconductivity when doped heavily with boron. The phenomena has been demonstrated in samples grown by chemic…
Ionic-liquid-gating setup for stable measurements and reduced electronic inhomogeneity at low temperatures
Yamaguchi Takahide, Yosuke Sasama, Hiroyuki Takeya +3
The ionic-liquid-gating technique can be applied to the search for novel physical phenomena at low temperatures because of its wide controllability of the charge carrier density. I…
Spin-induced anomalous magnetoresistance at the (100) surface of hydrogen-terminated diamond
Yamaguchi Takahide, Yosuke Sasama, Masashi Tanaka +4
We report magnetoresistance measurements of hydrogen-terminated (100)-oriented diamond surfaces where hole carriers are accumulated using an ionic-liquid-gated field-effect-transis…
Signature of high Tc around 25K in higher quality heavily boron-doped diamond
Hiroyuki Okazaki, Takanori Wakita, Takayuki Muro +7
Diamond has outstanding physical properties: the hardest known material, a wide band gap, the highest thermal conductivity, and a very high Debye temperature. In 2004, Ekimov et al…
Microscopic Evidence for Evolution of Superconductivity by Effective Carrier Doping in Boron-doped Diamond:11B-NMR study
H. Mukuda, T. Tsuchida, A. Harada +7
We have investigated the superconductivity discovered in boron (B)-doped diamonds by means of 11B-NMR on heteroepitaxially grown (111) and (100) films. 11B-NMR spectra for all of t…
Observation of superconducting gap in boron-doped diamond by laser-excited photoemission spectroscopy
K. Ishizaka, R. Eguchi, S. Tsuda +13
We have investigated the low energy electronic state of a boron-doped diamond thin film by the ultrahigh resolution laser-excited photoemission spectroscopy. We observed a clear sh…
