MENA5010 – Nanophysics
Schedule, syllabus and examination date
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.
