Electronic structure of beryllium acceptors confined in GaAs/AlxGa1-xAs quantum wells
2001 (English)Article in journal (Refereed) Published
A detailed experimental investigation is presented of beryllium acceptors confined in GaAs/AlxGa1-xAs quantum well structures in the presence of an applied magnetic field. A number of features related to the transitions between the acceptor ground and excited states are reported: (1) the satellites corresponding to the 1S-2S acceptor transition involving the different components [j = 3/2(G8) and j = 5/2(G7,8)] of the acceptor bound exciton (BE), where the labels of the exciton states are according to j-j coupling theory (or the cubic crystal-field scheme), (2) the detailed splitting of the 1S3/2(G6)-2S3/2(G6) acceptor transition involving the lowest acceptor BE state j = 5/2(G7,8), and (3) a component of the 1S-2P acceptor transition. In addition to this, the magnetic field dependence of these transitions is investigated experimentally, and the results are compared with theoretical predictions based on existing theory.
