Conduction electrons in acceptor-doped GaAs/GaAlAs heterostructures: a review
Wlodek Zawadzki, Andre Raymond, Maciej Kubisa
We review magneto-optical and magneto-transport effects in GaAs/GaAlAs heterostructures doped in GaAlAs barriers with donors, providing two-dimensional electron gas in GaAs quantum…

Conduction electrons localized by charged magneto-acceptors A in GaAs/GaAlAs quantum wells
M. Kubisa, K. Ryczko, I. Bisotto +3
A variational theory is presented of A and A centers, i.e. of a negative acceptor ion localizing one and two conduction electrons, respectively, in a GaAs/GaAlAs quan…

Photoluminescence investigations of 2D hole Landau levels in p-type single Al_{x}Ga_{1-x}As/GaAs heterostructures
M. Kubisa, L. Bryja, K. Ryczko +7
We study the energy structure of two-dimensional holes in p-type single Al_{1-x}Ga_{x}As/GaAs heterojunctions under a perpendicular magnetic field. Photoluminescence measurments wi…
