Five and three quantum dot systems as apparatuses for measuring energy-levels
Tetsufumi Tanamoto, Tomosuke Aono
A quantum dot (QD) system provides various quantum physics of nanostructures. So far, many types of semiconductor QD structures have been fabricated and investigated experimentally…
Simulations of hybrid charge-sensing single-electron-transistors and CMOS circuits
Tetsufumi Tanamoto, Keiji Ono
Single-electron transistors (SETs) have been extensively used as charge sensors in many areas such as quantum computations. In general, the signals of SETs are smaller than those o…
Reservoir Computing on Spin-Torque Oscillator Array
Taro Kanao, Hirofumi Suto, Koichi Mizushima +3
We numerically study reservoir computing on a spin-torque oscillator (STO) array, describing the magnetization dynamics of the STO array by a nonlinear oscillator model. The STOs e…
Hole spin resonance and spin-orbit coupling in a silicon metal-oxide-semiconductor field-effect transistor
Keiji Ono, G. Giavaras, Tetsufumi Tanamoto +3
We study hole spin resonance in a p-channel silicon metal-oxide-semiconductor field-effect transistor. In the sub-threshold region, the measured source-drain current reveals a doub…
Effects of interface electric field on the magnetoresistance in spin device
T. Tanamoto, M. Ishikawa, T. Inokuchi +2
An extension of the standard spin diffusion theory is presented by introducing a density-gradient (DG) term that is suitable for describing interface quantum tunneling phenomena. T…
Pseudosymmetric bias and correct estimation of Coulomb/confinement energy for unintentional quantum dot in channel of metal-oxide-semiconductor field-effect transistor
K. Ono, T. Tanamoto, T. Ohguro
We describe a measurement method that enables the correct estimation of the charging energy of an unintentional quantum dot (QD) in the channel of a metal-oxide-semiconductor field…
