This course reviews the basics of solid state physics, with
emphasis on semiconductor physics. We will begin with the crystal structures
and the classical aspects of free electron theory of metals, followed by the
properties of lattice vibrations. **Phonons**, within the harmonic crystal
oscillators and anharmonic models, will then be
discussed. Because of the practical need to explain many other phenomena that
cannot be understood within the classical picture, the concept of **band
structure **and Bloch states in periodic structures will be discussed. The
various topics in this section are: Fermi level, Fermi-Dirac
distribution, effective mass theorem, doping in semiconductors, and **transport
theory**, including mobility, scattering mechanisms, electron temperature,
screening, etc. **Optical properties **are to be reviewed. We will start
with a general discussion on dielectric constant and fundamental excitations.
Optical processes, including luminescence and Raman scattering, and their
general applications, will be discussed. **Surface** becomes more important
as devices are made smaller. We will review the important surface related
physics results on semiconductors, reduced dimensions, heterojunctions,
quantum wells, and the quantum Hall effect. **Magnetic properties** will be
briefly reviewed, and the subjects include the origin of magnetism, dia- and paramagnetism. **Superconductivity
and tunneling **diodes are to be discussed at the end.
