Abstract
Surface exciton polaritons are observed in a semiconductor for the first time. The modes are excited in ZnO crystals by the method of attenuated total reflection. Changing the angle of incidence of the ultraviolet radiation gives an experimental dispersion relation for surface exciton polaritons.Keywords
