Abstract
We present the recent results of the magneto-optical spectroscopy of low-di
mensional excitons in quantum wells (QWs), short period superlattices, quan
tum wires (QWRs) and quantum dots (QDs) in pulsed high magnetic fields prod
uced by three different techniques, electromagnetic flux compression, the s
ingle-turn coil technique and non-destructive long pulse magnets. The topic
s include the exciton spectra in GaAs/AlAs multi-QWs under ultrahigh magnet
ic fields up to 450 T, the field induced type I-type II transition in GaAs/
AlAs short period superlattices, the diamagnetic shift and the coupling of
quasi-1-dimensional excitons between QWRs grown at the giant steps in vicin
al planes of GaAs/AlAs QWs, and the diamagnetic shift of excitons in QDs co
nfined in tetrahedral shaped recesses (TSRs). (C) 1998 Elsevier Science B.V
