Monte Carlo Modeling of Spin-polarized Photoemission from p-doped GaAs Activated to Negative Electron Affinity
Oksana Chubenko, Siddharth Karkare, Dimitre Dimitrov +4
The anticorrelation between quantum efficiency (QE) and electron spin polarization (ESP) from a p-doped GaAs activated to negative electron affinity (NEA) is studied in detail usin…
A Chirality-Based Quantum Leap
Clarice D. Aiello, Muneer Abbas, John M. Abendroth +41
Chiral degrees of freedom occur in matter and in electromagnetic fields and constitute an area of research that is experiencing renewed interest driven by recent observations of th…
Enhancement of Photoemission on P-type GaAs using Surface Acoustic Waves
Boqun Dong, Andrei Afanasev, Rolland P. Johnson +1
We demonstrate that photoemission properties of GaAs photocathodes (PCs) can be altered by surface acoustic waves (SAWs) generated on the PC surface due to dynamical piezoelectric…
Contribution of σ-meson exchange to elastic lepton-proton scattering
O. Koshchii, A. Afanasev
Lepton mass effects play a decisive role in description of elastic lepton-proton scattering when the beam's energy is comparable to the mass of the lepton. The future MUSE experime…
Impact of Spatial Separation of Type-II GaSb Quantum Dots from the Depletion Region on the Conversion Efficiency Limit of GaAs Solar Cells
A. Kechiantz, A. Afanasev, J. -L. Lazzari
The purpose of this work is to look for a practical structure for application of quantum dots (QD) in solar cells in order to enhance sub-band gap photon absorption. We focuse on a…
Tuning up the performance of GaAs-based solar cells by inelastic scattering on quantum dots and doping of AlyGa1-ySb type-II dots and AlxGa1-xAs spacers between dots
A. Kechiantz, A. Afanasev
We used AlGaSb/AlGaAs material system for a theoretical study of photovoltaic performance of the proposed GaAs-based solar cell in which the type-II quantum dot (QDs) absorber is s…
