Schedule, syllabus and examination date

Choose semester

Course content

This course deals with non-ideal crystal structures. You learn how non-stoichiometric conditions affect network structures of materials, and the consequences this has on the physical-chemical properties of the compounds.

Learning outcome

When you have completed this course you can:

  • understand extended structures of relevant materials in terms of translational and rotational symmetry and analyze their packing, coordination and networks.
  • identify nonstoichiometry due to defects of varied dimensionality: point, 1D, 2D, 3D, and in modulated structures where a 3D lattice description is not sufficient.
  • use equilibria between point defects to describe the nonstoichiometry and its transport. You can use similar thermodynamic tools to describe formation of solid solutions.
  • sketch and interpret multicomponent phase diagrams that include nonstoichiometry and solid-solution formation and name their features.
  • classify phase transitions into several category groups, including symmetry and order parameters where applicable. You have a basic understanding of the Landau theory.
  • compile and present scientific information at peer-level in oral or written form


PhD candidates from the University of Oslo should apply for classes and register for examinations through Studentweb.

If a course has limited intake capacity, priority will be given to PhD candidates who follow an individual education plan where this particular course is included. Some national researchers’ schools may have specific rules for ranking applicants for courses with limited intake capacity.

PhD candidates who have been admitted to another higher education institution must apply for a position as a visiting student within a given deadline.


There will be 30 hours of lectures and 30 hours of seminars. In addition you will compile a written or oral presentation about a subject you choose in agreement with the person responsible for the course. in connection with the presentation there will also be a scientific discussion with the teacher and fellow students. The form of the presentation will be decided by the person responsible for the course early in the semester. The presentation must be approved before you can attend the exam


Oral exam (1 hour) counts 100 % of final grade. In addition you will give a written or oral presentation followed by a scientific discussion. The presentation must be approved before you can attend the exam

Grading scale

Grades are awarded on a pass/fail scale. Read more about the grading system.

Explanations and appeals

Resit an examination

This course offers both postponed and resit of examination. Read more:

Withdrawal from an examination

It is possible to take the exam up to 3 times. If you withdraw from the exam after the deadline or during the exam, this will be counted as an examination attempt.

Special examination arrangements

Application form, deadline and requirements for special examination arrangements.


The course is subject to continuous evaluation. At regular intervals we also ask students to participate in a more comprehensive evaluation.
