Case Studies with South Asian Soils,esistance: ρ(.) > ρ(0). The longitudinal magneto resistance, ρ.(.) (for .∥.) normally saturates at large .; that is, it tends to a constant value not very much greater than ρ(0). The behaviour of the transverse magnetoresistance, ρ.(.) (for .⊥.) is much more varied: in some metals it saturates, like

Anand J. Kulkarni,Naoufel Cheikhrouhoucattering will be dominant at high temperatures, but dies away at low temperatures, and scattering is then dominated by the static imperfections, in this case mainly the ionized impurities. We have already dealt with scattering by charged impurities in metals in sections 8.1 and 9.2, and exactly the

The Free-Electron Model,in the solid state are no longer bound to individual atoms, but are free to wander through the solid. A proper understanding of metallic or semiconducting behaviour could not begin, obviously, until the electron had been discovered by J.J. Thomson in 1897, but once this had happened, the significanc

But in practice, the equations can be solved at all easily only if most of the coefficients . are small (compared with ε., say). In the NFE approximation we assume that they are . small, so that the solution wave-functions
