ABSTRACT

In - crystalline alloy, , various optical, electrical and thermoelectric laws, relations, and coefficients, being enhanced by: our static dielectric constant law given in Equations (1a, 1b), accurate Fermi energy given in Eq. (11), and finally, in particular physical conditions given in Eq. (15), a same form of optical-and-electrical conductivities , determined in Equations (18, 20a) for optico-electrical and electro-optical phenomena, are now investigated, by basing on the same physical model and mathematical treatment method, as those used in our recent works[1, 2, 3], noting that, for x=0, these obtained numerical results are reduced to those given in the n(p)-type degenerate -crystal.[4,5] In the following, for given physical conditions, all the optical coefficients are expressed as functions of the effective photon energy : , E and , being the photon energy and the optical band gap. Then, some important remarks can be reported as follows. From our optical [electrical] conductivity model, , determined in Eq. (18), all the optical, electrical, thermoelectric coefficients are determined, as those given in Equations (19a-19d). In particular, for the optico-electrical phenomenon (O-EP), for which + , as that given in Eq. (15), one observes that the optical conductivity has a same form with that of the electrical conductivity for the electro-optical phenomenon (E-OP), , as those determined in Eq. (20a). One notes that this was used to determine the new laws, relations, and coefficients, investigated for the optical, electrical, and thermoelectric properties, observed in - crystalline alloy, as those reported in Table 3 and also in Equations (18, 19a-19d, 20a-20d, 21-31).
