PHYS 446 – |
Fall
2011 |
Objective: This
course integrates theory of Solid State Physics with experimental
demonstrations in the Research Physics Lab.
The course will provide a valuable theoretical introduction and an
overview of the fundamental applications of the physics of solids. This course
includes theoretical description of crystal and electronic structure, lattice
dynamics, and optical properties of different materials (metals,
semiconductors, dielectrics, magnetic materials and superconductors), based on
the classical and quantum physics principles. Several advanced experiments of
X-ray diffraction, Raman Scattering, Photoluminescence, etc., will be carrier out in the Research Physics Lab followed by their
theoretical discussion.

Prerequisites: PHYS 432 (E&M-I )
Homework:
10 %
Research
project: 10 %
Two
in-class exams: 15% each;
Homework
Assignments will be due weekly, usually on Thursdays. Assignments are due at the beginning of class.
Homework problems, lectures, and text readings will form the basis
of the exam problems.
Project
Students will perform a
research project on a selected topic of contemporary solid state physics. Each
student will study the specific effect of their choice by reviewing scientific journal
articles focusing on the effect chosen. A formal report will be written, with a
typical length of approximately 10 pages (double spaced). It should be well
organized and include an abstract, figures and reference section. The report
will be graded on the basis of its originality, clarity of expression, and
technical accuracy.
Exams:
There
will be two in-class exams and a final exam. The exams will be based on the
assigned homework problems, the assigned readings in the text, lecture notes,
and the lectures. Students are allowed to use lecture notes and formula sheets.
Not allowed to discuss the problems with other students.
Academic honesty
Students are encouraged to discuss the lectures and textbook material, work together on homework problems, and study together for exams. However, students are not allowed to present other people’s work as their own (including copying another student's homework as well as using of problem solutions found on the Internet or elsewhere).
