Abstract

The investigation of nanosecond ruby laser impact on Ge/Si heterostructures with Ge_xSi_1-x quantum dots (QD's) has been carried out. Both energy density in pulse and number of pulses changed. Raman spectroscopy was used to study the nanocluster states before and after laser irradiation. The method for control of composition and strain in Ge-Si based quantum dots was essentially improved.
