Abstract
An attempt is made to study the dia- and paramagnetic susceptibilities of electrons in quantum dots of optoelectronic materials in the prese nce of a parallel magnetic field, on the basis of a newly formulated e lectron dispersion law. It is found, taking n-Hg1-xCdxTe and In1-xGaxA syP1-y lattice-matched InP as examples that both susceptibilities incr ease with increasing electron concentration in oscillatory manners and increase monotonically with decreasing film thickness in the electric quantum limit. In addition, the numerical values of the susceptibilit ies in quaternary materials are greater than in the ternary compounds.
