ELECTROSTATICS OF A NANOWIRE INCLUDING NONLOCAL EFFECTS

We develop a method for calculating transverse static polarizability (per unit length) of a bulk nanowire by taking in to account the temporal and spatial dispersion. To describe these phenomena, we developed analytical theory based on local random phase approximation and plasmon pole approximation. Our theory is very general in the sense that it can be applied to any material which can be characterized by a bulk dielectric function of the form epsilon(omega,k). The theory is applied to calculate the transverse static polarizability of dielectric nanowire.
