Observation of a photo-emf that depends on the sign of the circular polarization of the light
Abstract
A new photogalvanic effect, predicted by Ivchenko and Pikus (1978), has been observed. When a tellurium crystal oriented along the C3 axis was exposed to CO2-laser radiation a photo-emf was observed, which reversed sign with reversal of the circular polarization of the light. The magnitude of the effect agrees with the theoretical estimates.
