Simulation for heat generation by the thin Au films using electromagnetic radiation. Calculated electromagnetic field distributions for the (a) 10 nm- and (b) 120-nm-thick Au films on a PMMA substrate. The wavelength of light is 450 nm with a normal incident angle. Corresponding resistive heat distributions for the (c) 10-nm- and (d) 120-nm-thick Au films on a PMMA substrate. (e) Calculated absorption spectra of the thin Au films with different thicknesses. (f) Light-to-heat conversion efficiency of the thin Au films averaged over emission wavelength from three different LEDs as a function of Au film thickness. The blue LED with the 450 nm peak wavelength shows the highest averaged light-to-heat conversion efficiency. LED, light-emitting diode; PMMA, poly(methyl methacrylate).
