ABSTRACT

In degenerate ( ) ( ) - crystalline alloy, , various optical, electrical and thermoelectric laws, relations, and coefficients, enhanced by: the optico-electrical phenomenon (O-EP) and the electro-optical phenomenon (E-OP), and our static dielectric constant law given in Equations (1a, 1b), accurate Fermi energy expression in Eq. (11), and conductivity model in Eq. (18), are now investigated, by basing on the same physical model and mathematical treatment method, as those used in our recent works.[1-5] One notes that, for x=0, this crystalline alloy is reduced to the n(p)-type degenerate -crystal. Some concluding remarks are given as follows. By basing on our optical [electrical] conductivity models, , given in Eq. (18), all the optical, electrical, thermoelectric coefficients have been determined, as those given in Equations (19a-19d, 20a-20d, 21-31). In particular, for the physical conditions, as those given in Eq. (15), one remarks that the optical conductivity, ,obtained from the O-EP, has a same form with that of the electrical conductivity, given from the E-OP, , as those determined in Eq. (20a), but since ( ) ( )( ), ( ) and , being the unperturbed reduced effective electron (hole) mass in conduction (valence) bands and the relative carrier mass, respectively. Finally, the numerical results of such optical, electrical and thermoelectric coefficients, calculated by using Equations (18, 19a-19d, 20a-20d, 21-31), are reported in Tables 3-10, suggesting the new ones.
