Surface Polaritons in Zinc PhosphideByE. Venger,T. Barlas,K. ShportkoFebruary 1st 2015SpectroscopyDispersion of surface polaritons in zinc phosphide (Zn3P2) single crystals is presented in this article for the first time. Surface polaritons in Zn3P2 were excited using the attenuated total reflectance (ATR) method.
