Electroluminescence in dopant-free GaAs/AlGaAs single heterojunctions: 2D free excitons, H-band, and the tidal effect
N. Sherlekar, S. R. Harrigan, L. Tian +9
Bright electroluminescence (EL) from dopant-free ambipolar lateral p-n junctions in GaAs/AlGaAs single heterointerface (SH) heterostructures is used to probe neutral free excitons…

Non-adiabatic single-electron pump in a dopant-free GaAs/AlGaAs 2DEG
B. Buonacorsi, F. Sfigakis, A. Shetty +7
We have realized quantized charge pumping using non-adiabatic single-electron pumps in dopant-free GaAs two-dimensional electron gases (2DEGs). The dopant-free III-V platform allow…
