Journal ArticleDOI
Electronic structure of silicon-based nanostructures
TL;DR: In this article, a tight-binding Hamiltonian was developed to account for the electronic properties of Si-based nanostructures, namely, Si graphene-like sheets and Si nanotubes.
Journal ArticleDOI
Large electrocaloric effects in oxide multilayer capacitors over a wide temperature range

TL;DR: High-quality multilayer capacitors of a perovskite oxide show that large electric-field-driven caloric effects could improve solid-state refrigeration technology and challenge today’s standard (based on magnetocaloric effects in gadolinium).
Journal ArticleDOI
Band structure of hydrogenated Si nanosheets and nanotubes
TL;DR: It is predicted that, for certain chiralities, hydrogenated Si nanotubes represent a new type of semiconductor, one with coexisting direct and indirect gaps of exactly the same magnitude.
Journal ArticleDOI
Is Silicene the Next Graphene
TL;DR: In this article, the authors present a review of the silicene, a relatively new allotrope of silicon, which can also be viewed as the silicon version of graphene, and discuss its synthesis and the challenges presented.
