dc.description.abstract | Raman scattering under hydrostatic pressure is used to investigate the phonon modes of self-organized Ge quantum dots (QD's) grown by solid source molecular-beam epitaxy. The pressure dependence of Ge-Ge phonon and Si acoustical-overtone (2TA) modes are studied from 0 to 67 kbar at room temperature. Our results show that the overlapping spectra of the Ge-Ge phonon and Si 2TA modes occur around 303 cm-1 at ambient pressure which can be resolved at relatively low pressure of about 3 kbar. The linear pressure coefficient of Ge-Ge phonon mode in QD's is found to be 0.29 cm-1/kbar, which is slightly smaller than the corresponding quantity in bulk Ge. | |
