The substrate cooling method was used in glancing angle deposition to grow a slanted silver nanorod array (NRA). Liquid nitrogen was allowed to flow under the substrate during deposition, and we compared the morphologies of Ag NRAs deposited with and without cooling. The cooling reduced the average width of the nanorods. A Z-shaped nanostructure array composed of three sections of silver NRAs was then deposited under the same cooling conditions. The average tilt angle of the nanorods from the surface normal was varied from the bottom section to the top section with the nanorods of the top section made to lie almost parallel to the substrate. Under normal illumination, the rods in the top section exhibit distinct longitudinal and transverse plasmon modes that cause strong polarization-dependent transmittance and reflectance.
The substrate cooling technique was introduced in glancing angle deposition to grow a slanted silver nanorod array (NRA) by introducing liquid nitrogen to flow under the substrate. The morphologies of NRAs deposited with cooling and without cooling are compared in this paper. During deposition, the temperature on the backside of substrate was kept at -140°C. A three-sectional zig-zag nanostructured array (ZNA) was then deposited under the same cooling condition. The polarization dependent transmittance and reflectance spectra of both NRA and ZNA were also measured and compared in this work.
