Abstract

Abstract The infrared reflection spectra of Bi 2Sr 2CaCu 2O 8 single crystals are measured with the ab plane for 30 – 5000 cm −1 at 2.7 and 293 K. The optical conductivity is calculated by the Kramers-Kronig transformation. The far infrared spectra in the gap region showed features of d wave pairing and strong peaks which are due to the exciton (internal excitation) of Cooper pair.
