Why density of state is proportional to the volume of the conductor in the case of ballistic transport?

13 October 2022 0 3K Report

Why the density of state is proportional to the volume of the conductor in the case of ballistic transport? For the bulk material, it is expressed as per cm^3 per eV but in ballistic transport, it is expressed as per eV only leading to the elimination of length term in Sharvin resistance.
