Superconductivity in Polycrystalline Diamond Thin Films
Yoshihiko Takano, Masanori Nagao, Tomohiro Takenouchi +4
Superconductivity was discovered in heavily boron-doped diamond thin films deposited by the microwave plasma assisted chemical vapor deposition (MPCVD) method. Advantages of the MP…
Advantage on Superconductivity of Heavily Boron-Doped (111) Diamond Films
Hitoshi Umezawa, Tomohiro Takenouchi, Yoshihiko Takano +8
The superconductivity transition temperatures Tc(onset) of 11.4 K and Tc(offset) of 7.4 K, which are the highest in diamond at present, are realized on homoepitaxially grown (111)…
Holes in the valence band of superconducting boron-doped diamond film studied by soft X-ray absorption and emission spectroscopy
Jin Nakamura, Tamio Oguchi, Nobuyoshi Yamada +8
Carbon- and boron-2 states of superconducting and non-superconducting boron-doped diamond samples are measured using soft X-ray emission and absorption spectroscopy. For the sup…
Superconductivity in CVD Diamond Thin Film Well-Above Liquid Helium Temperature
Y. Takano, M. Nagao, K. Kobayashi +5
Diamond has always been adored as a jewel. Even more fascinating is its outstanding physical properties; it is the hardest material known in the world with the highest thermal cond…
