✦ Synopsis

The effect of quenched impurities on the quantum critical behaviour of dilute Bose systems is investigated with the help of renormalization group and double e-expansion methods. It is shown that the presence of quenched impurities leads to an instability of the zero temperature quantum critical behaviour.

A new type of nonradiative process responsible for the excitonic luminescence quenching in (CdTe,CdCrTe)/CdMgTe heterostructures is identified and its efficiency is estimated. During this process, which belongs to the class of Auger-type nonradiative transitions, an immobilized exciton recombines no
