Fig. 5

a–d The measured emissivity spectra for four fabricated structures with different δ sizes of 140, 0, −140, and −280 nm, illustrated by the top-view SEM images shown in the upper panel. All scale bars correspond to 1 μm. e Comparison of the ECDs, Q-factors, and Lc between our results and those from some reported experimental works.
