The excel file contains all the data for the paper: Hironobu Takeya, James Frame, Takuo Tanaka, Yoshiro Urade, Xu Fang & Wakana Kubo, Bolometric photodetection using plasmon-assisted resistivity change in vanadium dioxide, Scientific Reports. The paper has 5 figures in total, with Figures 1 to 3 in the main text and Figures S1 and S2 in the supplementary. Only these figure panels have data: Figure 1(b): Resistivity hysteresis loop measured between the two electrodes before the fabrication of nanorods. Figure 2(a): Experimentally measured optical transmission and wavelength dependent resistivity of the sample, short axis. Figure 2(b): Numerically simulated transmission of the sample, short axis. Figure 3(a): Experimentally measured optical transmission and wavelength dependent resistivity of the sample, long axis. Figure 3(b): Numerically simulated transmission of the sample, long axis. Figure S1(a): Influence of the Drude damping of Ag on the zero-order transmission, short axis. Figure S1(b): Influence of the Drude damping of Ag on the zero-order transmission, long axis. Figure S2(a): Influence of metallic volume fraction on the zero-order transmission, short axis. Figure S2(b): Influence of metallic volume fraction on the zero-order transmission, long axis.
