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 holes into such an electron system leads to the formation of a hydrodynam

Determination of carrier density and dynamics via magneto-electroluminescence spectroscopy in resonant tunneling diodes

Autor: A. Naranjo, L. Worschech, Marcio D. Teodoro, G. E. Marques, E. R. Cardozo de Oliveira, Sven Höfling, Fabian Hartmann, Victor Lopez-Richard, Andreas Pfenning

We study the magneto-transport and magneto-electroluminescence properties of purely n-doped GaAs/Al$_{0.6}$Ga$_{0.4}$As resonant tunneling diodes with an In$_{0.15}$Ga$_{0.85}$As quantum well and emitter prewell. Before the resonant current condition

Magnetically controlled exciton transfer in hybrid quantum-dot–quantum-well nanostructures

Autor: Euclydes Marega, Greg Salamo, Z. Ya. Zhuchenko, E. R. Cardozo de Oliveira, Marcio D. Teodoro, Benito Alén, Yu. I. Mazur, Morgan E. Ware, V. Laurindo Jr., Georgiy G. Tarasov, G. E. Marques

A magnetophotoluminescence study of the carrier transfer with hybrid InAs/GaAs-quantum-dot-InGaAs-quantum-well structures is carried out where we observe an unusual dependence of the photoluminescence (PL) on the GaAs barrier thickness at strong magn

Electroluminescence on-off ratio control of n−i−n GaAs/AlGaAs-based resonant tunneling structures

Autor: G. E. Marques, E. C. dos Santos, L. Worschech, E. D. Guarin Castro, Victor Lopez-Richard, Fabian Hartmann, E. R. Cardozo de Oliveira, Marcio D. Teodoro, Sven Höfling, Andreas Pfenning

Publikováno v: Physical Review B. 98

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 of such a device is unveiled when the electrical output current chan

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/GaAsxSb1−x quantum dots. The latter causes visible Aharonov-Bohm oscillations and a change of

The study of the interaction of surface plasmon polaritons (SPPs) with quantum emitters has become very important in the last few years. The ability to design optical devices as well as investigate the physics of strongly interacting systems is some

Perspectives on high-frequency nanomechanics, nanoacoustics, and nanophononics

Autor: null Priya, E. R. Cardozo de Oliveira, N. D. Lanzillotti-Kimura

Publikováno v: Applied Physics Letters. 122(14):140501

Nanomechanics, nanoacoustics, and nanophononics refer to the engineering of acoustic phonons and elastic waves at the nanoscale and their interactions with other excitations such as magnons, electrons, and photons. This engineering enables the manipu
