Absorption spectrum of doped highly mismatched alloys
Hassan Allami, Jacob J. Krich
Highly mismatched alloys (HMA's) are a class of semiconductor alloys with large electronegativity differences between the alloying elements. We predict the absorption spectrum due…
Plasma frequency in doped highly mismatched alloys
Hassan Allami, Jacob J. Krich
Highly mismatched alloys (HMAs) have band structures strongly modified due to the introduction of the alloying element. We consider HMAs where the isolated state of the alloying el…
Optimizations of GaAs Nanowire Solar Cells
Anna H. Trojnar, Christopher E. Valdivia, Ray R. LaPierre +2
The efficiency of GaAs nanowire solar cells can be significantly improved without any new processing steps or material requirements. We report coupled optoelectronic simulations of…
Nonradiative lifetimes in intermediate band materials - absence of lifetime recovery
Jacob J. Krich, Bertrand I. Halperin, Alán Aspuru-Guzik
Intermediate band photovoltaics hold the promise of being highly efficient and cost effective photovoltaic cells. Intermediate states in the band gap, however, are known to facilit…
