We show results of our systematic investigation by means of quasi-elastic and inelastic laser light scattering (QEILS) of electron- and hole–phonon interactions as well as charge- and spin-density scattering mechanisms from hole gas fluctuations including their overlapping with phonon features by using near infrared excitation of doped bulk p-GaAs and self-assembled InAs/GaAs quantum dot (QD) structures. Additionally, results of our study of CdS and CdSe/ZnS QDs, multi-functionalized by peptides possessing strict affinity to integrins of MDA-MB-435 cancer cells are also presented.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
