PHYS-310 / 5 crédits
Enseignant: Yazyev Oleg
This course gives an introduction into Solid State Physics (crystal structure of materials, electronic and magnetic properties, thermal and electronic transport). The course material is at the level of Ashcroft & Mermin and is addressed to the 3rd year students in Physics.
Electrons in periodic potential (cont.): tight-binding approximation, Fermi surfaces and band structures of selected elements.
Dynamics of electrons in periodic potential: semiclassical model, electrical conductivity, concept of hole charge carriers and effective mass, dynamics in presence of magnetic field.
Lattice vibrations and thermal properties: vibrational modes within harmonic approximation, phonons, specific heat, anharmonic effects, thermal expansion, heat conductivity.
Semiconductors: general properties and band structures, impurities, intrinsic and doped semiconductors, concept of hole charge carriers and effective mass, optical adsorption and excitons, p-n junctions, light-emitting diods, photovoltaic cells, transistors, elements of quantum confinement and quantum transport.
Magnetism: magnetic susceptibility, magnetic Hamiltonian of an isolated ion, ferromagnetism and antiferromagnetism, Heisenberg exchange interaction, mean-field theory, itinerant magnetism, magnetocrystalline anisotropy, magnetic domains and domain walls.
Superconductivity: history of discovery and classification, electric, magnetic and thermal phenomenology, London theory, elements of the BCS theory.
