Geometric blockade in a quantum dot coupled to two-dimensional and three dimensional electron gases
K. Yamada, M. Stopa, T. Hatano +4
We fabricated a quantum dot coupled laterally to a two-dimensional electron gas and vertically to a three-dimensional electron gas in order to investigate the eigenstate dependence…

Vertically Coupled Double Quantum Dots Connected In Parallel
Shinichi Amaha, Tsuyoshi Hatano, Takashi Nakajima +1
We report charge transport measurements in a ring-shaped quadruple quantum dot system, composed of two vertically coupled double quantum dots connected in parallel. The vertical co…
