摘要：

In this communication we show that the cancelation of excitonic effects by photo-injected carriers can be easily produced in ZnSe-ZnTe superlattices. This combination is interesting: it has a type 11 band alignment in real space. Strong confinements of electrons and holes by large bands offsets lead to important values of Rydberg energies, thus, important energy-shifts of some 20 meV are measured when exciton screening is produced in such superlattices.
