Mr. Vallone, a Queens Democrat, said that opaque metal gates are unattractive and easily vandalized.
Transmission of light through a subwavelength aperture in regularly patterned opaque metal film is enhanced at resonant wavelengths.
As the phase transition takes place, the hafnium nitride film morphs from a conductive and opaque metal into an insulating and transparent semiconductor.
However, the existence of opaque metal layers could reduce the optical transparency of the MOM multilayer even though the MOM multilayer has a very low sheet resistance comparable to that of a metal electrode.
When the Au-coated SACNT thin film was put on the p-GaP, lots of carriers could spread outside the opaque metal electrode, which could have the possibility to contribute to the optical output power.
A thin film of an optically opaque metal such as aluminum, silver, or gold is coated along the outside walls of the tapered optical fiber tip to form an optical light pipe free of defects, which would permit photons to escape from the tapered sides of the optical fiber.
This is quite likely due to the fact that opaque metal-laden debris is often deposited in the bony defects.
Our planarized apertures are 40 250 nm diameter glass pillars surrounded by a thin, opaque metal and coated by 10 nm of SiO2.
The PMMA lens substrate and parylene cable are largely transparent, but the opaque metal electrodes and traces in the cable, which have a surface area of ~20%% of the area of the dilated rat pupil, do block a percentage of incident light.
