Optimizing GaAs/AlGaAs Growth on GaAs (111)B for Enhanced Nonlinear Efficiency in Quantum Optical Metasurfaces
T. Blaikie, M. C. Tam, S. Stich +2
This study is an optimization of GaAs and AlGaAs growth on GaAs (111)B substrates with a surface misorientation of 2° towards [11], aiming to enhance sur…
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…
Novel 3D Reciprocal Space Visualization of Strain Relaxation in InSb on GaAs Substrates
T. Blaikie, Y. Shi, M. C. Tam +2
This study introduces the Reciprocal Space Polar Visualization (RSPV) method, a novel approach for visualizing X-ray diffraction-based reciprocal space data. RSPV allows for the pr…
Observation of an Abrupt 3D-2D Morphological Transition in Thin Al Layers Grown by MBE on InGaAs surface
A. Elbaroudy, B. Khromets, F. Sfigakis +7
Among superconductor/semiconductor hybrid structures, in-situ aluminum (Al) grown on InGaAs/InAs is widely pursued for the experimental realization of Majorana Zero Mode quasiparti…
Coherence measurements of polaritons in thermal equilibrium reveal a power law for two-dimensional condensates
Hassan Alnatah, Qi Yao, Jonathan Beaumariage +7
We have created a spatially homogeneous polariton condensate in thermal equilibrium, up to very high condensate fraction. Under these conditions, we have measured the coherence as…
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…
Terahertz semiconductor laser source at -12 C
Ali Khalatpour, Man Chun Tam, Sadhvikas J. Addamane +3
Room temperature operation of Terahertz Quantum Cascade Lasers (THz QCLs) has been a long-pursued goal to realize compact semiconductor THz sources. The progress toward high-temper…
Semiconductor nanowire metamaterial for broadband near-unity absorption
Burak Tekcan, Brad van Kasteren, Sasan V. Grayli +6
The realization of a semiconductor near-unity absorber in the infrared will provide new capabilities to transform applications in sensing, health, imaging, and quantum information…
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…
