Introduction to Solid State Physics

About this programme

Content The course begins with a summary of concepts and relationships in quantum mechanics and statistical physics that are needed for elementary solid state physics. This is followed by a review of the structure of crystals. The course treats electrical and thermal properties of crystalline elements and the properties of these properties depending on various variables such as e.g. temperature. The free electron model and the near-free electron model are used to describe the electrical and thermal properties of simpler metals. The concept of holes is introduced for semiconductors and is applied to the electrical properties of intrinsic and extrinsic semiconductors. Lattice dynamics is described through the introduction of the phonon concept. The Debey model is used to describe heat capacity, volume expansion and thermal conductivity of insulators. The course includes compulsory laboratory work. The course comprises a theory module of 6.5 credits and a laboratory module of 1 credits. Expected study results To fulfil the goals of knowledge and understanding, the student should be able to: - describe the crystal structure of the most common cubic and hexagonal structures - explain how the reciprocal lattice can be used to explain X-ray scattering against crystals and define Brillouin zones - explain differences in the electrical conductivity between metals, insulators and semiconductors based on a band structure model. To fulfil the goals for proficiency and ability, the student should be able to: - perform calculations of reciprocal lattice parameters for cubic structures
