- Title

- Abstract
We report on the first observation of light-induced nonohmic current in a semiconductor nanostructure. The effect is revealed in an unbiased asymmetric InAs quantum well under excitation by far-infrared laser radiation in the presence of a tilted magnetic field. It is interpreted in terms of a nonzero toroidal moment of a two-dimensional electron gas. © 2002 MAIK “Nauka / Interperiodica”.
