Abstract:The authors report on the Raman scattering spectra and fundamental absorption edge of dense semiconductor-insulator nanocomposites. These were synthesized by injection of the semiconducting melt into the channels of dielectric matrices. The Raman spectra exhibit shifts, broadenings, and asymmetries consistent with phonon confinement in nanometre-size shifts, broadenings, and asymmetries consistent with phonon confinement in nanometre-size semiconductor crystallites. Nanoscale networks of small effective mass s… Show more
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.
