THEORETICAL CALCULATIONS OF THE TRANSITION ENERGIES OF A HYDROGENIC IMPURITY IN GAAS GAALAS MULTIQUANTUM WELLS IN MAGNETIC-FIELDS APPLIED AT ANY ANGLE/

Calculations are made of the energies of the dominant transition (1s t o 2p(+1)-like) of a hydrogenic donor impurity in a multi-quantum-well (MQW) system subject to a magnetic field applied at an angle theta to the direction of growth of the MQW layers. The model used involves con structing suitable basis states, and then performing a matrix diagonal ization procedure. The results are compared to the available experimen tal data, including the extreme cases of fields perpendicular (theta = 0 degrees) and parallel (theta = 90 degrees) to the layers. The resul ts are also found to compare well with the results of existing variati onal calculations.
