Aim

To provide an overview of physical properties of matter, primarily crystalline metals and semiconductors. Basic knowledge of condensed matter's optical and electrical properties, dependence on temperature, composition and doping is of great importance for later courses in the program.

Learning outcomes (after completion of the course the student should be able to)

  • account for the cubic crystal structures, as well as the terms lattice vectors and base
  • calculate the Miller index for an atomic plane and know how these are related to reciprocal lattice vectors
  • explain and give examples of the three common types of crystal bonds; ionic bonds, covalent bonds and metal binding
  • calculate spectra of lattice vibrations (phonons) for simple crystals and understand their relation to specific heat and heat conduction 
  • determining cubic crystal structure using x-ray diffraction
  • determine the structure and lattice constant by Bragg's law and with the diffraction condition in terms of reciprocal lattice vectors and extinction in terms of a structure factor
  • explain the meaning of the terms electron density, density of states, Fermi-Dirac's distribution function and Fermi energy, and be able to do calculations using the universal relationships between these
  • account for the free electron model
  • do calculations using Ohm's law and conductivity using the Drude model, as well as the connection with mobility
  • describe the reciprocal lattice for cubic crystals as well as explain the concepts of Brillouin Zones and Bragg planes
  • explain how a periodic potential gives rise to energy bands and energy gaps and how the electron distribution in the bands determines whether a substance becomes metal or insulator/semiconductor
  • explain the meaning of the concepts of effective mass, law of mass action, electrons, holes, n and p-doping, intrinsic and extrinsic behavior for doped semiconductors
  • calculate electron and hole densities, position of the chemical potential and electrical conductivity in a given semiconductor material with known doping and temperature
  • explain the Hall effect and use this to determine electron or hole density
  • calculate the size of the band gap for semiconductor given optical transmission data and/or temperature dependence of the conductivity
  • solve easier heat conduction and heat expansion problems
  • account for the key elements of thermodynamics, as well as the concepts of heat and pressure-volume work
  • treat idealized thermodynamic processes and calculate efficiencies for simple cycles

Examination including compulsory elements

A written examination at end of the cource. There is an optional midterm examination and optional exercise problems that give bonus points that can contribute to the grade. For a final mark also laboratory sessions must be passed.

The course examiner may assess individual students in other ways than what is stated above if there are special reasons for doing so, for example if a student has a decision from Chalmers on educational support due to disability.
