Figure 4: Spatial distribution of MIT temperature.
From: Striped nanoscale phase separation at the metal–insulator transition of heteroepitaxial nickelates
Maps of (a,b) TMI and TIM showing the transition temperature is a local property of the material. Three areas are encircled to indicate the order with which they become insulating (A, B and C) and revert to the metallic state (C, B and A). The map in (c) shows point-by-point the amount of insulating region at 140 K in a neighbouring area of radius 100 nm. Scale bar, 1 μm.
