The samples were grown by pulsed molecular beam epitaxy mode. Two types of samples have been investigated. In one type the InSb dots were capped with 200 monolayers of InP; in the other type no capping was deposited after the InSb dot formation. We observe two peaks in the Raman spectra of the uncapped dot, while only one peak is observed in the Raman spectra of the capped dots. In the case of the uncapped dots the peaks are attributed to LO-like and TO-like vibration of completely relaxed InSb dots, in agreement with high resolution transmission electron microscopy photographs. The Raman spectra of the capped dot suggest a different strain state in the dot due to the capping layer.This work has been supported by CICYT under project MAT95-0966 and the HCM program under network CT 330349.Peer reviewedAmerican Institute of Physics201020101997info:eu-repo/semantics/articlehttp://purl.org/coar/resource_type/c_6501512940 bytesapplication/pdfhttp://hdl.handle.net/10261/21580reponame:DIGITAL.CSIC.
