Heat and mass transport processes and crystallization kinetics
of nanosize epitaxial layers growth under pulse cooling of saturated
solution-melt have been studied. Photoluminescence spectra of heterostructures
so obtained containing a quantum well and of doped GaAs superlattices
are associated with optical transitions within the quantum-dimension
layer and in the case of superlattices, also with the recombination
across a band gap which is indirect in the real space.
