Diffusion of photo-excited holes in viscous electron fluid
Yu. A. Pusep, M. D. Teodoro, V. Laurindo +3
The diffusion of photo-generated holes is studied in a high-mobility mesoscopic GaAs\ channel where electrons exhibit hydrodynamic properties. It is shown that the injection of hol…
Determination of carrier density and dynamics via magneto-electroluminescence spectroscopy in resonant tunneling diodes
E. R. Cardozo de Oliveira, A. Naranjo, A. Pfenning +6
We study the magneto-transport and magneto-electroluminescence properties of purely n-doped GaAs/AlGaAs resonant tunneling diodes with an InGaAs q…
Magnetically controlled exciton transfer in hybrid quantum dot-quantum well nanostructures
V. Laurindo, Yu. I. Mazur, E. R. Cardozo de Oliveira +8
A magnetophotoluminescence study of the carrier transfer with hybrid InAs/GaAs quantum dot(QD)-InGaAs quantum well (QW) structures is carried out where we observe an unsual depende…
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…
