Atomic Effective Pseudopotentials for Semiconductors
J. R. Cárdenas, G. Bester
We derive an analytic connection between the screened self-consistent effective potential from density functional theory (DFT) and atomic effective pseudopotentials (AEPs). The mot…
Influence of the charge carrier tunneling processes on the recombination dynamics in single lateral quantum dot molecules
C. Hermannstädter, G. J. Beirne, M. Witzany +7
We report on the charge carrier dynamics in single lateral quantum dot molecules and the effect of an applied electric field on the molecular states. Controllable electron tunnelin…
Experimental imaging and atomistic modeling of electron and hole quasiparticle wave functions in InAs/GaAs quantum dots
G. Bester, D. Reuter, L. He +7
We present experimental magnetotunneling results and atomistic pseudopotential calculations of quasiparticle electron and hole wave functions of self-assembled InAs/GaAs quantum do…
Semiconductor quantum dots with light-hole exciton ground state: fabrication and fine structure
Y. H. Huo, B. J. Witek, S. Kumar +11
Quantum dots (QDs) can act as convenient hosts of two-level quantum szstems, such as single electron spins, hole spins or excitons (bound electron-hole pairs). Due to quantum confi…
