Lingering Times at Resonance: The Case of Sb-based Tunneling Devices
Edgar David Guarin Castro, Andreas Pfenning, Fabian Hartmann +7
Concurrent natural time scales related to relaxation, recombination, trapping, and drifting processes rule the semiconductor heterostructures' response to external drives when char…
Optical mapping of non-equilibrium charge carriers
E. David Guarin Castro, A. Pfenning, F. Hartmann +6
We investigate the energy relaxation segmentation in a resonant tunneling heterostructures by assessing the optical and transport dynamics of non-equilibrium charge carriers. The e…
Electroluminescence on-off ratio control of n-i-n GaAs/AlGaAs-based resonant tunneling structures
E. R. Cardozo de Oliveira, A. Pfenning, E. D. Guarin +7
We explore the nature of the electroluminescence (EL) emission of purely n-doped GaAs/AlGaAs resonant tunneling diodes (RTDs) and the EL evolution with voltage. A singular feature…
Topology driven g-factor tuning in type-II quantum dots
J. M. Llorens, V. Lopes-Oliveira, V. López-Richard +8
We investigate how the voltage control of the exciton lateral dipole moment induces a transition from singly to doubly connected topology in type II InAs/GaAsSb quantum dots. The l…
Collective modes of trapped spinor Bose condensates
C. Trallero-Giner, Darío G. Santiago-Pérez, V. Romero-Rochin +1
We study the richer structures of quasi-one-dimensional Bogoliubov-de Genes collective excitations of F = 1 spinor Bose-Einstein condensate in a harmonic trap potential loaded in a…
Electron-acoustic-phonon interaction in core/shell Ge/Si and Si/Ge nanowires
Darío G. Santiago-Pérez, C. Trallero-Giner, G. E. Marques
General expressions for the electron- and hole-acoustical-phonon deformation potential Hamiltonian (H_{E-DP}) are derived for the case of Ge/Si and Si/Ge core/shell nanowire struct…
