Local transport in a disorder-stabilized correlated insulating phase
M. Baenninger, A. Ghosh, M. Pepper +4
We report the experimental realization of a correlated insulating phase in 2D GaAs/AlGaAs heterostructures at low electron densities in a limited window of background disorder. Thi…
Acoustic charge transport in n-i-n three terminal device
Marco Cecchini, Giorgio De Simoni, Vincenzo Piazza +3
We present an unconventional approach to realize acoustic charge transport devices that takes advantage from an original input region geometry in place of standard Ohmic input cont…
Ultra low threshold current THz quantum cascade lasers based on buried strip-waveguides
S. Dhillon, J. Alton, S. Barbieri +5
THz quantum cascade lasers based on a novel buried cavity geometry are demonstrated by combining double-metal waveguides with proton implantation. Devices are realised with emissio…
Surface acoustic wave-induced electroluminescence intensity oscillation in planar light-emitting devices
Marco Cecchini, Vincenzo Piazza, Fabio Beltram +5
Electroluminescence emission from surface acoustic wave-driven light-emitting diodes (SAWLEDs) is studied by means of time-resolved techniques. We show that the intensity of the SA…
