Parameterisation of the model of dispersion dependences of solid state optical constants

Acta Physica Slovaca 48 (1998) 451–458

In this paper the new model of dispersion of the optical constants of the amorphous solids is presented. This model adds to the Lorentz model of the classical oscillator the quantum-mechanical concept of the gap. Moreover, this model respects the existence of the tail in absorption of the amorphous material. It is necessary to point out that this new model is acceptable from all the point of physics. It can be employed for solving the inversion problem within the fields of both optics of thin films and optics of solids. The results obtained for a thin film of hydrogenated amorphous silicon using our new model are introduced as well.
