A dissertation submitted to the Faculty of Science, University of
the Witwatersrand, Johannesburg, in fulfilment of the
requirements for the degree of Master of Science. / The properties-of systems which undergo a metal-insulator
(MI) transition are currently being extensively studied. Both the
transport and thermodynamic properties of these MI systems
show interesting behaviour, particularly near the MI transition.
A complete theory to describe MI systems does not yet exist.
In the present work the focus is on the thermodynamic
properties of MI systems, in particular on the specific heat and
susceptibility. The thermodynamic properties in the absence of
a magnetic field are now well understood, with models such as
the two-fluid model giving a good account of the behaviour.
In finite magnetic fields the thermodynamic properties are
even more interesting and varied. It is the aim of the present
work to develop and test models to explain the effects of
applying magnetic fields to MI systems. The focus is mainly on
phosphorous doped silicon, and the results are gratifying. The
theory should, however, also apply to other similar MI systems. / Andrew Chakane 2018
