ABSTRACT

In degenerate n^+ (p^+ )-p(n)- X(x)≡GaTe(1-x)P(x)- crystalline alloy, 0≤x≤1, various optical, electrical and thermoelectric laws and Stokes-Einstein-Sutherland-Reynolds-Van Cong relations, enhanced by: the optico-electrical phenomenon (O-EP) and the electro-optical phenomenon (E-OP), our static dielectric constant law given in Equations (1a, 1b), our accurate Fermi energy expression given in Eq. (11), and finally our conductivity model given in Eq. (18), are now investigated, by basing on the same physical model and the 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 GaTe -crystal. Some concluding remarks are given as follows. -By basing on our optical [electrical] conductivity models, σ_(O[E]), 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 opticalconductivity, σ_O, obtained from the O-EP, has a same form with that of the electrical conductivity, given from the E-OP, σ_E, as those determined in Eq. (20a), but σ_O>σ_E since m_r (x)<m_c(v) (x), m_c(v) and m_r, 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 3-13, suggesting a same viscosity phenomenon observed in both liquids and solids.
