Write down the original of the quantum resistance.

Ans. There is generally no scattering along the conduction path, since L << Lm, Lϕ and we might have expected that the resistance of the “channel would be zero that mean infinite channel conductance. In ballistic transport model, there are no collisions and interactions, [...]

Derive the formula for quantum resistance and conductance in ballistic transport.

Ans. To characterize ballistic transport, we need to determine the resistance of the channel. We assume that a potential V is applied across the two reservoirs in fig. 4.4, positive on the left side, driving a current in the wire. The Fermi energy in [...]

Define the classical resistance and conductance.

Ans. Resistance is defined in electrical circuit theory by Ohm's law i.e.,                                                                           …(i) where, V is the voltage across a circuit element and I is the resulting current that flows through the element. In general, considering two arbitrarily shaped conductors immersed in a conducting medium characterized [...]
