Analysis staff creates hybrid resonant metasurfaces with configurable structural colours
Directed development of amorphous silicon nanocups a) Scheme depicting the fabrication technique of nanocup metasurfaces together with i) metallic deposition ii) spin coating of double layer resist iii) electron beam publicity iv) directed development of a-Si by way of sputtering v) lift-off. b) Chosen scanning electron micrographs of the a-Si nanocup arrays highlighting: open resonator…
