Spin-dependent current through a quantum dot from spin-polarized non-equilibrium quantum Hall edge channels
Haruki Kiyama, Takashi Nakajima, Soichiro Teraoka +2
We report selective injection of both spin-up and spin-down single electrons into a quantum dot (QD) from spin-polarized non-equilibrium quantum Hall edge channels (ECs) generated…
Tuning the electrically evaluated electron Lande g factor in GaAs quantum dots and quantum wells of different well widths
G. Allison, T. Fujita, K. Morimoto +9
We evaluate the Lande g factor of electrons in quantum dots (QDs) fabricated from GaAs quantum well (QW) structures of different well width. We first determine the Lande electron g…
Single Photoelectron Detection after Selective Excitation of Electron-Heavy Hole and Electron-Light Hole Pairs in Double Quantum Dots
K. Morimoto, T. Fujita, G. Allison +9
We demonstrate the real-time detection of single photogenerated electrons in two different lateral double quantum dots made in AlGaAs/GaAs/AlGaAs quantum wells having a thin or a t…
Excitation spectroscopy of few-electron states in artificial diatomic molecules
T. Hatano, Y. Tokura, S. Amaha +3
We study the excitation spectroscopy of few-electron, parallel coupled double quantum dots (QDs). By applying a finite source drain voltage to a double QD (DQD), the first excited…
Aharonov-Bohm Oscillations Changed by Indirect Interdot Tunneling via Electrodes in Parallel-Coupled Vertical Double Quantum Dots
T. Hatano, T. Kubo, Y. Tokura +3
Aharonov-Bohm (AB) oscillations are studied for a parallel coupled vertical double quantum dot with a common source and drain electrode. We observe AB oscillations of current via a…
Transport properties of two laterally coupled vertical quantum dots in series with tunable inter-dot coupling
T. Hatano, S. Amaha, T. Kubo +5
We describe the electronic properties of a double dot for which the lateral coupling between the two vertical dots can be controlled in-situ with a center gate voltage (Vc) and the…
