Abstract

In the review, properties of strongly localised excitons are discussed. Strongly localised excitons are observed at low temperatures in some of the CdTe/CdMnTe heterostructures. The effect of strong localisation of excitons becomes more pronounced in structures with large Mn fraction in the CdMnTe barriers and also in some of modulation n-type doped structures. In consequence of a strong localisation, quite new properties of excitons are observed. Several such properties are discussed in the work.
