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…
Dynamic Nuclear Polarization in Double Quantum Dots
M. Gullans, J. J. Krich, J. M. Taylor +6
We theoretically investigate the controlled dynamic polarization of lattice nuclear spins in GaAs double quantum dots containing two electrons. Three regimes of long-term dynamics…
On the chemical bonding effects in the Raman response: Benzenethiol adsorbed on silver clusters
Semion K. Saikin, Roberto Olivares-Amaya, Dmitrij Rappoport +2
We study the effects of chemical bonding on Raman scattering from benzenethiol chemisorbed on silver clusters using time-dependent density functional theory (TDDFT). Raman scatteri…
Electronic Structure of Multiple Dots
M. Stopa, A. Vidan, T. Hatano +2
We calculate, via spin density functional theory (SDFT) and exact diagonalization, the eigenstates for electrons in a variety of external potentials, including double and triple do…
Single-dot spectroscopy via elastic single-electron tunneling through a pair of coupled quantum dots
T. Ota, K. Ono, M. Stopa +7
We study the electronic structure of a single self-assembled InAs quantum dot by probing elastic single-electron tunneling through a single pair of weakly coupled dots. In the regi…
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…
