Thickness-Dependent Dielectric Constant of Few-Layer In<sub>2</sub>Se<sub>3</sub> Nanoflakes
Thickness-Dependent Dielectric Constant of Few-Layer In<sub>2</sub>Se<sub>3</sub> Nanoflakes
The dielectric constant or relative permittivity (εr) of a dielectric material, which describes how the net electric field in the medium is reduced with respect to the external field, is a parameter of critical importance for charging and screening in electronic devices. Such a fundamental material property is intimately related …
