A diverse array of semiconductor-based composite materials have been prepared,
characterized, and utilized in many applications ranging from photocatalysis, photovoltaic
cells, photoelectrochromic displays, and light-emitting devices to sensors. The composite
architectures (nanoarchitectures in many cases) are equally diverse. In this review, we
highlight the advances that have been made and identify some of the gaps in our current
knowledge of these materials. Size quantization effects and semiconductor quantum dots
are also discussed.
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.
