Though there are other uses for nanowires beyond these, the only ones that actually take advantage of physics in the nanometer regime are electronic. [51] In addition, nanowires are also being studied for use as photon ballistic waveguides as interconnects in quantum dot/quantum effect well photon logic arrays. Photons travel inside the tube ...
In mesoscopic physics, a quantum wire is an electrically conducting wire in which quantum effects influence the transport properties. Usually such effects appear in the dimension of nanometers, so they are also referred to as nanowires .
They vary widely, however, due to highly localized regions of the nanowires where the effective cross-sectional area for superconducting current is reduced. [29] SNSPD devices have also demonstrated exceptionally low jitter – the uncertainty in the photon arrival time – as low as 3 picoseconds at visible wavelengths.
The morphology of the nanowires allowed the electrons to have a direct pathway to the photoanode. This form of solar cell exhibits 50–60% internal quantum efficiencies. [101] Nanowires with quantum dot coatings on silicon nanowires (SiNW) and carbon quantum dots.
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.
Bundles of wires can be used to enhance tribological properties of polymers, with applications in actuators and potentiometers. It has been recently proposed that twisted nanowires could work as electromechanical nanodevices (or torsion nanobalances) to measure forces and torques at nanoscale with great precision. [14]
Nanofabrication can be used to construct ultradense parallel arrays of nanowires, as an alternative to synthesizing nanowires individually. [ 3 ] [ 4 ] Of particular prominence in this field, Silicon nanowires are being increasingly studied towards diverse applications in nanoelectronics, energy conversion and storage.
Nanowires and nanotubes: The elastic moduli of some nanowires namely lead and silver, decrease with increasing diameter. This has been associated with surface stress, oxidation layer, and surface roughness. [62] However, the elastic behavior of ZnO nanowires does not get affected by surface effects but their fracture properties do.
