Resonant Raman-scattering in 3 - 5- and 2 - 6 -semiconductors and heterostructures

The physics and technology of heterostructures of 3 - 5-and of 2 -6-materials are rapidly growing films with promising developments in the future. After compiling some basic relations of the microscopic theory of Raman scattering for the off-resonance and in-resonance case, we start with a report on collective intersubband excitations in p-doped GaAs/(Al, Ga)As multiple quantum wells and on the effects of subband nonparabolicity in these samples. Next we concentrate on a detailed investigation of the electronic spin flip in semimagnetic (cd, Mn)Te and on the optically detected paramagnetic resonance signal (PRS) from the localized 3d5-electrons of Mn2+ in the same material
