- Title
Conductance of a 2D Electron System at Low Frequencies.
- Authors
Shikin, V. B.
- Abstract
Low-frequency features of the conductance of a 2D electron system are considered. It is shown that, in addition to the parameter ωτ(ωistheexternalfrequencyandτistheelasticrelaxationtime), which occurs in the frequency dependence of the 3D conductivity in the Drude approximation, the 2D conductance contains other dimensionless combinations that involve the external frequency and the 2D conductivity. The notion of the “mobility” of a 2D system as the quantity governing the deviation of the conductance of the 2D system with ac current from its conductance under stationary conditions is introduced. Experimental data testifying to the presence of the discussed features of the 2D conductance are presented. © 2000 MAIK “Nauka / Interperiodica”.
