Figure 2

Average temperature change ΔT of the VO2 gap in the dimer under the 5 nW/μm2 LWIR irradiation (red solid line) and the corresponding end-to-end resistance normalized by the room temperature resistance R/R0 (blue solid line). For comparison, average temperature change of a perfect absorbing VO2 film with the same thermal time constant (red dashed line) and the film’s normalized resistance (blue dotted line) are also displayed.
