  2. Nanowire - Wikipedia

    en.wikipedia.org/wiki/Nanowire

    Nanowires also show other peculiar electrical properties due to their size. Unlike single wall carbon nanotubes, whose motion of electrons can fall under the regime of ballistic transport (meaning the electrons can travel freely from one electrode to the other), nanowire conductivity is strongly influenced by edge effects.

  3. Nanocircuitry - Wikipedia

    en.wikipedia.org/wiki/Nanocircuitry

    Until a few years ago, transistors and nanowires were put together to produce the circuit. However, scientists have been able to produce a nanowire with transistors in it. In 2004, Harvard University nanotech pioneer Charles Lieber and his team have made a nanowire—10,000 times thinner than a sheet of paper—that contains a string of ...

  4. Electrical breakdown - Wikipedia

    en.wikipedia.org/wiki/Electrical_breakdown

    Electrical breakdown in an electric discharge showing the ribbon-like plasma filaments from a Tesla coil.. In electronics, electrical breakdown or dielectric breakdown is a process that occurs when an electrically insulating material (a dielectric), subjected to a high enough voltage, suddenly becomes a conductor and current flows through it.

  5. Quantum wire - Wikipedia

    en.wikipedia.org/wiki/Quantum_wire

    One consequence of this quantization is that the classical formula for calculating the electrical resistance of a wire, R = ρ l A , {\displaystyle R=\rho {\frac {l}{A}},} is not valid for quantum wires (where ρ {\displaystyle \rho } is the material's resistivity , l {\displaystyle l} is the length, and A {\displaystyle A} is the cross ...

  6. Molecular wire - Wikipedia

    en.wikipedia.org/wiki/Molecular_wire

    Most types of molecular wires are derived from organic molecules. One naturally occurring molecular wire is DNA.Prominent inorganic examples include polymeric materials such as Li 2 Mo 6 Se 6 [1] and Mo 6 S 9−x I x, [2] [3] [4] [Pd 4 (CO) 4 (OAc) 4 Pd(acac) 2], [5] and single-molecule extended metal atom chains (EMACs) which comprise strings of transition metal atoms directly bonded to each ...

  7. Silicon nanowire - Wikipedia

    en.wikipedia.org/wiki/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.

    Smartwatches are a hot-ticket gift over the holidays, but a new study might have you rethink how you strap the device to your wrist in the future.

  9. Breakdown voltage - Wikipedia

    en.wikipedia.org/wiki/Breakdown_voltage

    Breakdown voltage is a characteristic of an insulator that defines the maximum voltage difference that can be applied across the material before the insulator conducts. In solid insulating materials, this usually [citation needed] creates a weakened path within the material by creating permanent molecular or physical changes by the sudden current.
