Spin effects in single-electron transport through carbon nanotube quantum dots (2007)
Moriyama, Satoshi, Fuse, Tomoko, Yamaguchi, Tomohiro, Ishibashi, Koji
We investigate the total spin in an individual single-wall carbon nanotube quantum dot with various numbers of electrons in a shell by using the ratio of the saturation currents of the first steps of...
Superconducting SET with tunable electromagnetic environment (2002)
Watanabe, Michio, Ishibashi, Koji, Aoyagi, Yoshinobu
We have studied the environmental effect on superconducting single-electron transistors (S-SETs) by biasing S-SETs with arrays of small-capacitance dc SQUIDs, whose effective impedance can be varied...
