Ov. Volkov, SELF-CONSISTENT CALCULATION OF LANDAU-LEVELS OF A QUASI-2-DIMENSIONALHOLE GAS AT A GAAS ALGAAS P-TYPE HETEROJUNCTION/, Physics of the solid state, 40(6), 1998, pp. 1019-1027
An efficient method is proposed for the self-consistent calculation of
Landau levels of a quasi-two-dimensional hole gas at a GaAs/AlGaAs he
terostructure in a perpendicular magnetic field. The method is based o
n transforming the Schroedinger and Poisson equations to a system of n
onlinear differential equations which are then spatially discretized a
nd solved by the method of relaxation. The method proposed is used to
model the optical spectra for recombination of the quasi-two-dimension
al hole gas with electrons localized at: a delta layer of donors in an
isolated p-type heterojunction. Particular attention is paid to effec
ts associated with the dependence of the wave functions and shape of t
he potential well on the magnetic field, which have not been considere
d before. (C) 1998 American Institute of Physics.
