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…
Fully spin-dependent transport of triangular graphene flakes
Tomoya Ono, Tadashi Ota, Yoshiyuki Egami
The magnetic moment and spin-polarized electron transport properties of triangular graphene flakes surrounded by boron nitride sheets (BNC structures) are studied by using first-pr…
Few-electron molecular states and their transitions in a single InAs quantum dot molecule
T. Ota, M. Rontani, S. Tarucha +6
We study electronic configurations in a single pair of vertically coupled self-assembled InAs quantum dots, holding just a few electrons. By comparing the experimental data of non-…
Molecular states observed in a single pair of strongly coupled self-assembled InAs quantum dots
T. Ota, M. Stopa, M. Rontani +8
Molecular states in a SINGLE PAIR of strongly coupled self-assembled InAs quantum dots are investigated using a sub-micron sized single electron transistor containing just a few pa…
