Electric field (EF) effects on two-dimensional (2D) layered materials are extensively utilized in developing functional devices. Since silicene has an analogous electronic structure to graphene, it is expected to be utilized in highly-functional 2D materials. Furthermore, silicene field effect transistor was very recently reported. Thus, the EF effects on silicene are increasingly attracted to develop new functional devices. In this study, we performed first-principles calculations of the EF effects on silicene-amine 2D systems focusing on the electronic interactions at the silicene-amine interface. We analyzed the Si-N chemical bond and the electronic polarizations, and thereby revealed the mechanism of electronic structure change induced by the applied EF.
