From: Extreme magnetoresistance at high-mobility oxide heterointerfaces with dynamic defect tunability
Schematic illustrations of the semiclassical magnetotransport in high perpendicular magnetic fields when high-mobility electrons (a) are strictly confined in 2D, (b) are restricted to move vertically by a disorder potential in some locations (red vertical line) but allowed in other locations (black vertical lines) and (c) are heated to reduce the mean-free path with the thermal energy exceeding the disorder potential variations, which leads to unrestricted vertical movement.
