Charge dynamics in the Kondo insulator Ce3Bi4Pt3
Abstract
We report the reflectivity and optical conductivity of the Kondo insulator Ce3Bi4Pt3. For temperatures less than 100 K, depletion of the conductivity below about 300 cm-1 signifies the development of a charge gap. The temperature dependence of the disappearance of the spectral weight scales with the quenching of the Ce 4f moments. © 1994.
