Hot-carrier optoelectronic devices based on semiconductor nanowires
Jonatan Fast, Urs Aeberhard, Stephen P. Bremner +1
In optoelectronic devices such as solar cells and photodetectors, a portion of electron-hole pairs are generated as so called hot carriers with an excess energy that is typically l…
Photocarrier extraction in GaAsSb/GaAsN type-II QW superlattice solar cells
Urs Aeberhard, Alicia Gonzalo, Jose María Ulloa
Photocarrier transport and extraction in GaAsSb/GaAsN type-II quantum well superlattices are investigated by means of inelastic quantum transport calculations based on the non-equi…
Ab-initio analysis of structural, electronic, and optical properties of a-Si:H
Philippe Czaja, Urs Aeberhard, Massimo Celino +2
We present a first-principles study of the structural, electronic, and optical properties of hydrogenated amorphous silicon (a-Si:H). To this end, atomic configurations of a-Si:H w…
Theoretical investigation of direct and phonon-assisted tunneling currents in InAlGaAs-InGaAs bulk and quantum well interband tunnel junctions for multi-junction solar cells
Urs Aeberhard
Direct and phonon-assisted tunneling currents in InAlGaAs-InGaAs bulk and double quantum well interband tunnel heterojunctions are simulated rigorously using the non-equilibrium Gr…
