NEGATIVELY CHARGED EXCITON-X- IN QUANTUM-WELLS WITH STRONG MAGNETIC-FIELD

In this paper we present a theoretical study of X- in an infinite rect angular quantum well with a strong magnetic field perpendicular to the well layer. Using a variational calculation, we have calculated the b inding energies of X- (the energy required to remove one of the two el ectrons from X- to infinity), as functions of the ratio of the electro n conduction band mass to the hole valence band mass, sigma = m(e)/m(h ). The results in the two-dimensional and three-dimensional limits agr ee with the theoretical results obtained by other authors.
