SOLID STATE PHYSICS
Learning outcomes of the course unit
The aim of the course is to achieve an understanding of Solid State Physics and to be able to use it in accounting for the structural, thermal and electromagnetic behaviour of crystalline solids.
Good working knowledge of advanced calculus: functions of two or more variables, differential equations, functions of complex variables, Fourier transforms.
Good working knowledge of classical mechanics, thermodynamics, electricity and magnetism, quantum mechanics, classical and quantum statistical mechanics, atomic and molecular physics.
