Research on II-VI heterostructures in high magnetic fields : Recent results

Recent results of transport and optical experiments on HgTe quantum wells and HgSe films in high and ultra-high magnetic fields are reported. New data on spin injection from the semimagnetic semiconductor BeMnZnSe into GaAs are given, using BeMnZnSe as a spin aligner or a BeTe/ZnMnSe/BeTe double barrier resonant tunneling diode. New data on the magneto-luminescence of modulation doped ZnSe/ZnBeMgSe/ZnSe quantum wells clearly showing many body effects are presented.
