Welcome!

Our research is focused on fundamental properties of two-dimentional electrons hosted in semiconductor quantum structures, such as GaAs/AlGaAs heterostructures and quantum wells. The most remarkable phenomena discovered in such systems, when it is subject to high magnetic field and low temperature, are integral (Nobel Prize, 1985) and fractional (Nobel Prize, 1998) quantized Hall effects.

Our current efforts are centered on recently discovered non-equilibrium phenomena emerging in weak magnetic fields, when the system is exposed to microwave radiation and/or dc electric fields. The most remarkable non-equilibrium effect is, the so called, radiation-induced zero-resistance states. Interested graduate students may find these references useful:
