Abstract
Breakdown of non-conductive state of Corbino discs at integer filling factors of Landau levels at high source-drain voltages has been measur ed for samples fabricated from GaAs/Al0.3Ga0.7As heterostructures. Cri tical breakdown electric fields at the filling factors of 1, 2, 4 and 6 are in agreement with the critical breakdown Hall electric fields in the quantized Hall plateaus with these quantum numbers measured in bu tterfly-type Hall bars.
