Exchange interaction effects in the thermodynamic properties of quantum dots
Luis G. Dias da Silva, Nelson Studart
We study electron-electron interaction effects in the thermodynamic properties of quantum-dot systems. We obtain the direct and exchange contributions to the specific heat C_v in t…
Oscillatory spin relaxation rates in quantum dots
C. F. Destefani, Sergio E. Ulloa
Phonon-induced spin relaxation rates in quantum dots are studied as function of in-plane and perpendicular magnetic fields, temperature and electric field, for different dot sizes.…
Modeling of transport through submicron semiconductor structures: A direct solution to the Poisson-Boltzmann equations
D. Csontos, S. E. Ulloa
We report on a computational approach based on the self-consistent solution of the steady-state Boltzmann transport equation coupled with the Poisson equation for the study of inho…
Spatially resolved manipulation of single electrons in quantum dots using a scanned probe
A. Pioda, S. Kicin, T. Ihn +7
The scanning metallic tip of a scanning force microscope was coupled capacitively to electrons confined in a lithographically defined gate-tunable quantum dot at a temperature of 3…
Anisotropic electron g-factor in quantum dots with spin-orbit interaction
C. F. Destefani, Sergio E. Ulloa
g-factor tuning of electrons in quantum dots is studied as function of in-plane and perpendicular magnetic fields for different confinements. Rashba and Dresselhaus effects are con…
Decoherence of Rabi oscillations in a single quantum dot
J. M. Villas-Boas, Sergio E. Ulloa, A. O. Govorov
We develop a realistic model of Rabi oscillations in a quantum-dot photodiode. Based in a multi-exciton density matrix formulation we show that for short pulses the two-level model…
