The problem of an extrinsic surface optical polaron, bound to an impurity atom, near the surface is investigated for the first time in the framework of a recently developed canonical transformation method. Energy and wave function for all ranges of the coupling constant (α) and the impurity parameter (β) are obtained numerically following the canonical transformation method. For a strong impurity the relatively unimportant effect due to the image potential is neglected. The dependence of the energy, the wave function, and the induced potential on α, β are obtained and shown graphically.
