Theoretical prediction of semiconducting bilayer graphene by ionic molecules

We theoretically predict the possibility of controlling the band-gap and carrier type of bilayer graphene by using ionic molecules. We can control the semiconducting carrier type (intrinsic, p-type, or n-type) of bilayer graphene sandwiched by ionic molecules by changing the cation-anion pair.
