Physics of disordered materials
This course is intended for graduate students in physics, chemistry and interdisciplinary materials science. A basic course in solid state physics (for example based on C. Kittel: Introduction to solid state physics) is a desirable prerequisite. The course is given in English.
Aim: To be able to read research papers in the field of disordered materials science, by gaining familiarity with basic physical concepts.
Literature: Lecture notes.
Further reading: N.E. Cusack: The Physics of Structurally Disordered Matter, Adam Hilger, Bristol, 1987. S.R. Elliott: Physics of Amorphous Materials, Longman, London, 1984.
Credits: 6 ECTS credits
Examination: Hand-in assignments that will be distributed during the course.
Responsible: Gunnar Niklasson, Department of Engineering Sciences,The Ångström Laboratory, Room 4412. Tel: 018-4713101 email: firstname.lastname@example.org
