Answer 1

Explanation:

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 nanowireQuantum wires are extremely narrow structures where electron transport is possible only in a very few transverse modes (with energies less than the Fermi energy). Quantum wires can be used as electron waveguides.

Nanotubes can also be used as quantum wires.If the material size is reduced in 3 dimensions up to the length scale where quantum effects come into play, then the material becomes a quantum wire

Answer 2

1). An electrical conducting wire in which quantum effect influence the transport properties. this effect appear in the small dimension in nanometre.

they also called as nanowires.

2). quantum hall effect - it is observed in two dimensional electron system which appear in low temperatures and strong magnetic fields, in which the Hall conductance σ undergoes quantum Hall transitions to take on the quantized values.

values

$\sigma = \frac{I_\text{channel}}{V_\text{Hall}} = \nu \; \frac{e^2}{h}$
