Electron Conductivity Multiplied by Velocity as Proportional to Optical Potential
M.A. Grado-Caffaro and M. Grado-Caffaro
We show that, in a given solid, the product of the electrical conductivity and the (averaged) electron velocity is proportional to the corresponding optical potential. For simplicity, we assume a quasi-one-dimensional solid as, for example, a metallic or semiconductor nanowire. In addition, ballistic and diffusive electron transports are discussed.
