<p> The theoretical formulation of the electronic
transport properties (in the absence of a magnetic field)
of pure single crystals of simple metals is extended to
incorporate the effect of a non~spherical Fermi surface,
using a multiple orthogonalized plane wave description
of the conduction electrons. Two approaches are
considered, one using a variational principle, and the
other employing a scattering time approximation. </p> <p> Formal results for the electrical resistivity and
the electronic contribution to the thermal resistivity
are expressed in terms of effective phonon frequency
distributions. These distributions are particularly
convenient for numerical computations and are
generalization: of those previously used for the case of
a spherical Fermi surface. </p> <p> The generalization of the scattering time method
to dilute nonmagnetic substitutional alloys is applied
to hexagonal close~packed metalsc It is shown that the
addition of small amounts of impurities to pure Zn leads
to measurable changes in the temperature dependence of
the electrical resistivity ratio (see text for ratio with symbols). The corresponding
deviations front Matthiessen's rule for polycrystalline
samples are also calculated. </p> / Thesis / Master of Science (MSc)
