Abstract

Magnetophotoluminescence- and photoluminescence-excitation-spectroscopy experiments are performed up to 5 T at 1.7 K in a 111 -grown CdTe/Cd0.93Mn0.07Te superlattice. The results are compared with calculations of the level energies and of the exciton binding energies, that include field-induced negative offsets. A type-I type-II transition is evidenced near 2 T and a value of 15 20% of the bandgap energy difference is deduced for the valence-band offset. © 1990 The American Physical Society.
