Full control of quadruple quantum dot circuit charge states in the single electron regime
M. R. Delbecq, T. Nakajima, T. Otsuka +4
We report the realization of an array of four tunnel coupled quantum dots in the single electron regime, which is the first required step toward a scalable solid state spin qubit a…
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…
Kondo effects in a triangular triple quantum dot with lower symmetries
A. Oguri, S. Amaha, Y. Nishikawa +4
The triangular triple quantum dot is an interesting system which can demonstrate various types of the Kondo effects, such as the one due to the local spin S=1 moment caused by the…
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…
