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…
Quantum interferometry with a g-factor-tunable spin qubit
K. Ono, S. N. Shevchenko, T. Mori +2
We study quantum interference effects of a qubit whose energy levels are continuously modulated. The qubit is formed by an impurity electron spin in a silicon tunneling field-effec…
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…
Electronic magnetization of a quantum point contact measured by nuclear magnetic resonance
Minoru Kawamura, Keiji Ono, Peter Stano +2
We report an electronic magnetization measurement of a quantum point contact (QPC) based on nuclear magnetic resonance (NMR) spectroscopy. We find that NMR signals can be detected…
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…
Resistive detection of nuclear spins in a single quantum dot under Kondo effect regime
Minoru Kawamura, Daniel Gottwald, Keiji Ono +2
We study dynamic polarization and resistive detection of nuclear spins in a semiconductor quantum dot (QD) under the Kondo effect regime. We find that the differential conductance…
