Abstract:We investigated current-voltage characteristics of a lattice-mismatched GaAs(n)/Si(p) heterojunction. For low bias voltages at 77 K it exhibits a behaviour characteristic of the Coulomb blockade. We discuss why this unexpected phenomenon can occur in the investigated structures.PACS numbers: 73.40. Gk, 73.40.Kpa, 61.72.Lk Fabrication of GaAs-based structures on Si substrates gives possibilities of easy integration of silicon electronics with optical devices. A major obstacle for a success of such technology… 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.
