Fig. 3

The wire (80 µm × 1 µm × 50 nm) on top of a glass substrate is coated with a 200-nm-thick film of 1 and Joule-heated by the application of an electrical current of 4 mA. a Optical reflectivity (λ = 452 nm) images ΔR/R = (RON−ROFF)/ROFF of the nanowire recorded at selected base temperatures Tb. The dotted lines indicate the position of the corresponding isotherm (TSCO = 64 °C). b Contour map of the surface temperature acquired from gathering the isotherms for various base temperatures (ΔT = TSCO − Tb). Scale bars, 20 µm.
