Zinc-blende Mn1−xMnxTe - A new diluted magnetic semiconductor system

ABSTRACTIn contrast to the bulk diluted magnetic semiconductor (DMS) Cd1−xMnxSe which occurs with the wurtzite structure, its epilayers grown on (001) GaAs substrate by Molecular Beam Epitaxy exhibit the cubic zinc-blende structure. Raman spectroscopy and photoluminescence studies on this novel DMS show (1) a “two-mode” behavior of the zone center optical phonons, (2) the Raman line associated with the spin-flip in the Zeeman split S = 5/2 ground state of Mn2+, and (3) large Raman shifts associated with the spin-flip of donor-bound electrons. The large magnetic field dependence in (3) with saturation at high fields and low temperature shows that the s-d exchange interaction characteristic of DMS's is also manifested strikingly in the zinc-blende phase of Cd1−xMnxSe.
