NEW DIFFUSION-MOBILITY-VISCOSITY-ACTIVATION ENERGY-FERMI ENERGY RELATIONS, INVESTIGATED IN N(P)-TYPE DEGENERATE (OR VISCOUS) GaSb(1-x) As(x)-CRYSTALLINE ALLOY, SUGGESTING A DEGENERACY-AND-VISCOSITY EQUIVALENCE CONCEPT (XX)

In degenerate - crystalline alloy, , 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 -crystals. 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. Then, by basing on our optical electrical conductivity models, , 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.
