ABSTRACT

In degenerate n^+ (p^+ )-p(n)- X(x)≡GaAs(1-x)Sb(x)- crystalline alloy, 0≤x≤1, various optical and electrical 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 (1), this crystalline alloy is reduced to the n(p)-type degenerate GaAs (GaSb)-crystals. For the physical conditions, as those given in Eq.[15] one remarks that the optical conductivity, 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. Then, by basing on our optical [electrical] conductivity models, σ_(O[E]), given in Eq.[18] the diffusion-mobility-viscosity-activation energy-Fermi energy relations are determined, and their numerical results are reported in Tables 3n(p), 4n(p), 5n(p) and 6n(p), suggesting an equivalence between the degeneracy-and-viscosity concept in this X(x)-degenerate (viscous) crystalline alloy.
