Effect of Dielectric Constant Mismatch on Plasmons in Cylindrical Semiconductor Quantum Wires

The dielectric response function of the electron system in a cylindrical semiconductor quantum wire is derived within the random phase approximation by using the linear response theory in the quantum limit when the only lowest electron subband is assumed to be occupied. The plasmon dispersion is obtained as a root of the dielectric function in which the mismatch of dielectric constants of the wire material and the barrier one is taken into account.
