Low-frequency dynamics of bounded 2D electron system in strong magnetic field
Grodnenskii I. M. , Kamaev A. Yu
The response of a 2D electron system in a magnetic field В has been found to depend on the frequency in a region well below the known characteristic frequencies. The effect arises when the size of the 2D system, L, becomes comparable to the length lEf which determines the region in which the induced edge potential is localized. A method for con tactless measurements of the conductivity σχχ is proposed.
