Current distribution and Hall potential landscape towards breakdown of the quantum Hall effect: a scanning force microscopy investigation
We present line- and area-scans of the Hall potential landscape of a two-dimensional electron system (2DES) in narrow (AlGa)As-based Hall bars under quantum Hall (QH) conditions, obtained by low-temperature scanning force microscopy. For several magnetic field values B in the regime of the QH platea...
