We report our investigation on piezoreflectance spectra (PZR) of a conventional InAs quantum dots (CVQD) and an InAs/In0.15Ga0.85As dots-in-a-well (DWELL). A large red-shift of ground state QD0 between two samples is attributed mainly to larger size of DWELL induced by the activated strained-driven decomposition.
