    en.wikipedia.org/wiki/Superconducting_nanowire...

    The superconducting nanowire single-photon detector (SNSPD or SSPD) is a type of optical and near-infrared single-photon detector based on a current-biased superconducting nanowire. [1] It was first developed by scientists at Moscow State Pedagogical University and at the University of Rochester in 2001.

    en.wikipedia.org/wiki/Nanowire_lasers

    Nanowire lasers can be grown site-selectively on Si/SOI wafers with conventional MBE techniques, allowing for pristine structural quality without defects. Nanowire lasers using the group-III nitride and ZnO materials systems have been demonstrated to emit in the visible and ultraviolet, however infrared at the 1.3–1.55 μm is important for telecommunication bands.

  5. Nanolaser - Wikipedia

    en.wikipedia.org/wiki/Nanolaser

    Plasmonic nanolaser sensors have recently been demonstrated that can detect specific molecules in air and be used for optical biosensors. Molecules can modify the surface of metal nanoparticles and impact the surface recombination velocity of gain medium of a plasmonic nanolaser, which contributes to the sensing mechanism of plasmonic nanolasers.

  6. Silicon nanowire - Wikipedia

    en.wikipedia.org/wiki/Silicon_nanowire

    Schematic of silicon nanowire. Silicon nanowires, also referred to as SiNWs, are a type of semiconductor nanowire most often formed from a silicon precursor by etching of a solid or through catalyzed growth from a vapor or liquid phase. Such nanowires have promising applications in lithium-ion batteries, thermoelectrics and sensors.

  7. Nanowire - Wikipedia

    en.wikipedia.org/wiki/Nanowire

    Corn-like nanowire is a one-dimensional nanowire with interconnected nanoparticles on the surface, providing a large percentage of reactive facets. TiO 2 corn-like nanowires were first prepared by a surface modification concept using surface tension stress mechanism through a two consecutive hydrothermal operation, and showed an increase of 12% ...

  8. Photon counting - Wikipedia

    en.wikipedia.org/wiki/Photon_counting

    Photon counting eliminates gain noise, where the proportionality constant between analog signal out and number of photons varies randomly. Thus, the excess noise factor of a photon-counting detector is unity, and the achievable signal-to-noise ratio for a fixed number of photons is generally higher than the same detector without photon counting.

  9. Niobium nanowire - Wikipedia

    en.wikipedia.org/wiki/Niobium_nanowire

    Niobium nanowires in form oxide or nitride are used to detect single photons at low temperatures. The superconducting nanowire single-photon detector is an example of something made from these nano-structured materials. [1]
