Vertically aligned carbon nanotubes (VACNTs) are excellent broadband (UV–VIS–IR) absorbers of light that can be made even darker with plasma treatments. Modification of VACNTs using O2 and/or CF4 plasmas is shown to have a significant impact on the reflectance and water repellency. Unfortunately, while O2 plasma treatment reduces the reflectance of VACNTs by changing the top surface morphology, it...
Transition edge sensors have demonstrated near unity detection efficiency of single photons and photon number resolving ability over a wide wavelength range (≈ 700–1600 nm). They are also known to be slow, with timing jitter values in the ≈ 100 ns range, and the best current values in the ≈ 20ns range. We report measured jitter times below 5ns for a tungsten TES. This is particularly relevant for...
