Solid State Theory

Valid for: 2021/22

Faculty: Faculty of Engineering, LTH

Decided by: PLED N

Date of Decision: 2021-04-19

Main field: Nanoscience.

Elective for: F4, F4-tf, F4-nf, MNAV1, N4-nf

Language of instruction: The course will be given in English

The course shall provide a better understanding of central concepts in solid state physics and their relation to the basic theories of quantum mechanics and electrodynamics. The students shall learn how these concepts can be applied to model physical effects quantitatively. Particular emphasis is given towards topics relevant to ongoing research in solid state physics and nanoscience in Lund.

Knowledge and understanding

For a passing grade the student must

- understand the concept of electronic bandstructure in crystals and be able to relate it to basic quantum mechanics,
- be able to estimate how scattering processes affect the transport properties in semiconductors and metals,
- be able to explain the microscopic origin of para-, dia-, and ferromagnetism within simplified models,
- understand the concept of a mean field approximation,
- have a comprehension how the dielectric function in a solid is affected by phonons, optical transitions and many-particle interactions,
- have an overview of superconductivity and have some knowledge of the microscopic BCS ground state

Competences and skills

For a passing grade the student must

- be able to apply envelope function to the modeling of semiconductor heterostructures,
- be able to handle simple problems in many-particle quantum theory using the occupation number representation,
- be able to execute elementary quantitative calculations for optical properties of solids, such as the gain spectrum of a semiconductor laser,

Judgement and approach

For a passing grade the student must

- be able to value the hierarchy of concepts in solid state physics,
- be able to see the utility of basic theoretical physics for practical problems.

Band structure of crystals and semiconductor heterostructures, Electron transport and scattering processes, Magnetism, Density matrix formalism and optical Bloch equations for semiconductor lasers, Dielectric properties, Coulomb interaction and excitons, Superconductivity

Grading scale: TH - (U,3,4,5) - (Fail, Three, Four, Five)

Assessment: Assessment takes the form of an oral examination.

The examiner, in consultation with Disability Support Services, may deviate from the regular form of examination in order to provide a permanently disabled student with a form of examination equivalent to that of a student without a disability.

Assumed prior knowledge: FFFF05 Solid State Physics or FFFF01 Electronic Materials; FMFN01 Quantum Mechanics Advanced Course or similar; Basic knowledge of electromagnetism and statistical physics.

The number of participants is limited to: No
