WebAug 7, 2024 · Two sets of five different Au gratings were fabricated, one set on a 90 nm thick flat Au layer and the other on a 142 nm thick flat Au layer. All five gratings in a set have an amplitude of 44 nm, a period of 6 μm, but different duty cycle of 1.25%, 2.08%, 4.16%, 8.33%, and 16.66%, corresponding to ridge linewidths of 75 nm, 125 nm, 250 nm ...

WebDiffraction gratings, like prisms, disperse white light into individual colors. If the grating spacing (d, the distance between slits) is known and careful measurements are made of … WebSubmicron scale sinusoidal gratings have been fabricated with nanometer thick Gold/Palladium film coated on 30% pretensioned polydimethylsiloxane substrates. Due to competition between the soft elastomeric substrates and relatively stiff films, periodic wavy profiles are created upon releasing the pretension. sims 3 black sims download
