Abstract

The effect of reduced dimensionality on the shape and position of the first order phonon bands in the Raman scattering spectrum of semiconductors is described. Off-resonance and resonance Raman scattering from semiconductor nanoparticles and superlattices are then considered. Results on nanocrystal size determination, lattice ordering and crystallization of amorphous ultra-thin films, interface induced stress, phase separation of supersaturated solid solutions, interface alloying and the electronic structure are presented..

Keywords
