Figure 3From: Hybrid FIB milling strategy for the fabrication of plasmonic nanostructures on semiconductor substrates Hybrid milling optical characterisation. (a) Zero-order transmission spectra of the SPPCs in structures A-E. (b) Transmission dispersion measured for SPPCs fabricated using optimum hybrid FIB milling strategy (Structure E). Lines represent the estimation of SPPC band gap using the Bragg conditions.Back to article page
