Using density functional theory with a semiempirical van der Waals approach proposed by Grimme, the adsorption behavior of carbon monoxide on a gold monolayer supported by graphene or monolayer hexagonal boron nitride has been investigated. Based on the changes in the Dirac cone of graphene and...

We investigate field effect transistors (FETs) based on semiconducting armchair-edged silicene nanoribbons (ASiNRs) by using ab initio quantum transport calculations. These FETs have high performance with an I <Subscript>on</Subscript>/I <Subscript>off</Subscript> ratio of over 10<Superscript>6</Superscript> and a subthreshold swing as small as 90 mV/decade....</superscript></subscript></subscript>
