Valley degeneracy in biaxially strained aluminum arsenide quantum wells
S. Prabhu-Gaunkar, S. Birner, S. Dasgupta +2
This paper details a complete formalism for calculating electron subband energy and degeneracy in strained multi-valley quantum wells grown along any orientation with explicit resu…

Single-valley high-mobility (110) AlAs quantum wells with anisotropic mass
S. Dasgupta, S. Birner, C. Knaak +4
We studied a doping series of (110)-oriented AlAs quantum wells (QWs) and observed transport evidence of single anisotropic-mass valley occupancy for the electrons in a 150 Åwide Q…

Donor binding energy and thermally activated persistent photoconductivity in high mobility (001) AlAs quantum wells
S. Dasgupta, C. Knaak, J. Moser +5
A doping series of AlAs (001) quantum wells with Si delta-modulation doping on both sides reveals different dark and post-illumination saturation densities, as well as temperature…
