Introduction to Research Seminar

Very clean two-dimensional electron systems can be realized on the interface of two semiconductors, such as GaAs and AlGaAs, by molecular beam epitaxy. The most remarkable phenomena discovered in such systems, when it is subject to high magnetic field and low temperature, are integral (Nobel Prize, 1985 - http://nobelprize.org/nobel_prizes/physics/laureates/1985/press.html) and fractional (Nobel Prize, 1998 - http://nobelprize.org/nobel_prizes/physics/laureates/1998/illpres/) quantized Hall effects. Over the past few years it was realized that various classes of magnetoresistance oscillations (other than Shubnikov-de Haas oscillations) can appear in these systems when subject to microwaves, dc electric fields, elevated temperatures, or their combinations. This seminar will survey recent experimental and theoretical developments in this growing field of non-equilibrium quantum transport.
