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)…
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…
Growth of R-123 Phase Single Crystal Whiskers
Masanori Nagao, Mitsunori Sato, Yukitake Tachiki +6
Single-crystal whiskers of R1Ba2Cu3Ox (R-123, R= La, Nd, Sm, Eu, Gd, Dy, Ho, Er, Tm, Yb and Lu) phase have been successfully grown by the Te- and Ca-doping method. The whiskers wer…
