Abstract
Development of an ellipsometry to the case of a coherent far infrared irradiation, low temperatures and small samples is described, includin g a decision of the direct and inverse problems of the convergent beam ellipsometry for an arbitrary wavelength, measurement technique and a compensating orientation of cryostat windows. Experimental results ar e presented: for a gold film and UBe13 Single crystal at room temperat ure (lambda = 119 mum), temperature dependencies of the complex dielec tric function of SrTiO3 (lambda = 119, 84 and 28 mum) and of YBa2Cu3O7 -delta Ceramic (lambda = 119 mum).
