Description
A model of semi-infinite semiconductor superlattice topped with a metal-insulator(M-I-SL) is suggested. A modified Giuliani-Quinn surface plasmon is found. It is interesting to note that the frequency and critical wavelength can be arbitrarily chosen by varying thickness of the insulator. In particular, a new type of surface plasmon with null critical wave vector exists only below the bulk plasmon continuum, and the frequency is directly related to the ratio of thickness of the insulator d to the superlattice spacing a.
