A grating with SU-8 epoxy spacer 28 nm, followed by Rh800 embedded in thinner epoxy 18 nm layer; gratings strips substructure: Ti 5 nm, 30 nm Ag, 40 nm alumina, 5 nm Ti, 30 nm Ag, and 10 nm alumina. The periodicity of the gratings is ~310 nm. The e-beam writing parameters were as follows: dose was 650, 725, 750, and 800 μC/cm2 for A, B, C, and D, respectively; 1.2 nA; and 100 kV accelerating voltage.
