|Title:||Effect Of Exciton Condensation On The Optical Refraction Index Of Cds|
|Abstract:||Detailed measurements of the transmission spectrum of CdS under high pumping excitation were performed. A variation of the refractive index with increasing excitation power is observed. This we attribute to the increase in the number of photoinjected carriers. A saturation of the effect is observed for intensities above a certain level. A simple model is used to evaluate the concentration of photoinjected carriers the saturated regime which turns out to be approximately 1.4 x 1018 cm-3. It is shown that the results are compatible with the assumption of formation of an electron- hole liquid (EHL) in CdS. © 1977.|
