A basic understanding of solids is
important for practicing physicists in all areas of study, and for many other
related disciplines as well. This course provides a basic understanding of what
makes solids behave the way they do, how they are studied, and the basic
interactions which are important. This course is provided as an elective for
Physics majors, Applied Physics majors, and majors in other related
disciplines. Traditionally, solid state physics
is introduced relatively late in an undergraduate physics course because a
familiarity with quantum theory, and in particular, the Schrödinger equation is
required. However, since many aspects of solid state physics have important
technological application, there is an increasing tendency to introduce the
subject in the second year of an undergraduate course as a preparation for the
advanced Solid State Physics modules which will be offered in the 3 The main aim of this module is to
give a description of crystal lattices, common crystal structures obtained by
adding a basis of atoms to the lattice, and the definition and properties of the
reciprocal lattice. Diffraction measurements are studied as tools to quantify
crystal lattices, including Bragg's law and structure factors. The
various types of atomic bonding, e.g., Van der Waals, ionic, covalent, metallic
and hydrogen are surveyed. Models of crystal binding are generalized to include
dynamics, first for classical lattice vibrations and then for quantized lattice
vibrations known as phonons. These concepts are used to calculate the heat
capacities of insulating crystals, to introduce the concept of density of
states, and to discuss phonon scattering.

Turton,
There
will be six sets of tutorial problems. You will have two weeks to complete each
assignment. Solutions will be available on the course site at edveNTUre the
morning after the problem sets are due. Your solutions will be graded
and returned during lecture as soon as possible.
·
A ONE
hour mid-term examination will cover materials from L0 to L16.
·
A
two and a half hour final examination will cover materials from lecture 1 to
lecture 33.
Problem sets and quizzes 15%, mid-term exam 25%, final 60% |
