摘要：

The fluctuations of the microwave electromotive force in the magnetic field state with an extremely low conductivity have been revealed in 2D electronic Corbino disks prepared based on GaAs/AlAs heterostructures. The experimental data are attributed to the spatial inhomogeneity and time instability of the electronic states that have zero conductivity and are induced by microwave radiation in the 2D Corbino disks at high filling factors.
