Course content

Nanoscience is referred to as a research area devoted to studies of various phenomena in small-size devices. It is a cross-disciplinary field including physics, chemistry and to some extent biology.

The heart of nanoscience is mesoscopic physics. The word ``meso'' reflects the fact that the size of the systems under consideration is located between microscopic (atoms) and macroscopic scales. In particular, it includes the systems dominated by elemental quantum processes – single-electron tunneling, ballistic and single-spin transport, Coulomb blockade.

Mesoscopic physics is based upon quantum theory; it includes quantum mechanics and statistics of interacting particles, physics of irreversible processes, physics of random systems, etc. At present time, mesoscopic physics - both experimental and theoretical - is a research topic of the majority of research groups at many universities and high-tech companies.

The course aims at an introduction to basic principles of nanophysics allowing working in research and development in nanotechnology. Students will learn basic principle of physics of nanometer-size systems with a focus on basic physical phenomena. In addition to elucidating the basic theoretical concepts, main application to existing and future electronics, including devices for realization of quantum computation algorithms, will be discussed.

Admission

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.

Prerequisites

Recommended previous knowledge

A Bachelors degree from the Bachelors program Materials and Energy for the future, or equivalent.

Teaching

This is an intensive course where the lectures most likely will be arranged as a 2-week seminar-like program. This course has a clone on master level. PhD students will be given an extra set of exercises and additional work during lectures.

Access to teaching

A student who has completed compulsory instruction and coursework and has had these approved, is not entitled to repeat that instruction and coursework. A student who has been admitted to a course, but who has not completed compulsory instruction and coursework or had these approved, is entitled to repeat that instruction and coursework, depending on available capacity.

Examination

Compulsory student presentations.

Examination support material

No examination support material is allowed.

Grading scale

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