Pulsed Electroluminescence in a Dopant-free Gateable Semiconductor
S. R. Harrigan, F. Sfigakis, L. Tian +7
We report on a stable form of pulsed electroluminescence in a dopant-free direct bandgap semiconductor heterostructure which we coin the tidal effect. Swapping an inducing gate vol…
High transparency induced superconductivity in field effect two-dimensional electron gases in undoped InAs/AlGaSb surface quantum wells
E. Annelise Bergeron, F. Sfigakis, A. Elbaroudy +7
We report on transport characteristics of field effect two-dimensional electron gases (2DEG) in 24 nm wide indium arsenide surface quantum wells. High quality single-subband magnet…
Stable electroluminescence in ambipolar dopant-free lateral p-n junctions
Lin Tian, Francois Sfigakis, Arjun Shetty +11
Dopant-free lateral p-n junctions in the GaAs/AlGaAs material system have attracted interest due to their potential use in quantum optoelectronics (e.g., optical quantum computers…
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…
