Abstract:
Low-dimensional characteristics of excitons confined in a quantum well (QW) are studied by applying a high magnetic field ( B ). The diamagnetic shift is best fit with a linear combination of linear and quadratic terms of B . From the quadratic dependence of B , it is obtained that the exciton becomes two-dimensional (2-D) like when the QW width decreases to 15 monolayers (ML). However, the 2-D confinement becomes weak when the width becomes smaller than 10 ML. In large B , the field confinement becomes significant in the electron-hole recombination, and the population inversion of the photo-generated carriers in the islands of ML fluctuation was observed.
