Graphene’s Electric Response
Researchers at Harvard record an oscillating electric response of multilayer grapheme, dependent upon electric field strength. They report that one of the implications is that the dielectric constant of grapheme is not, indeed, constant, but can change with the application of an external electric field. As a result, fundamental quantities like electron-electron interactions are now able to be controlled using the external electric field.
