Abstract

The complex dielectric tensor of quaterthiophene crystals is reported as deduced from ellipsometry measurements on single crystals and compared with that calculated on the basis of the microscopic theory. The internal reflectivity at the interface between the crystal and air has been derived, enabling discussion of the effect of self-waveguiding of the emission on the basis of the components of the material dielectric tensor.
