The potential ,; many-body effects,hoice of .(.) is itself a subtle and difficult problem, because (4.1) is only an approximation to a much more complicated equation, and .(.) has to be chosen in such a way as to make the approximation as good as possible. It is worth looking briefly at this more complicated equation, just to see wha

Magnetoresistance and Hall Effect,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

Radio-Frequency, Optical and Other Properties, At room temperature and above, the properties of real metals are described by essentially the same equations, suitably generalized: in (2.27), for example, σ. will then be given by (9.13), and τ must be replaced by some suitable average if τ. varies with .. But in pure metals at low temperatures an

Carriers in Semiconductors,nd the empty conduction bands above ε. (Fig. 5.9). Because of this gap, the number of carriers (electrons and holes) varies rapidly with temperature in a semiconductor, whereas it is essentially temperature-independent in a metal, and our first task is to look at this temperature variation.
