Mean Free Path of Electrons Calculator

In thermodynamics, mean free path can be calculated in Copper from the atomic weight, valence electrons and density.
Note: Copper have one free electron per atom. Electron mean free path of (Copper) Cu to be 55 nm.

Formula:

U = VE * ro / Aw Ep = 829.4 * U C1 = 53.4 - 20.8 * U C2 = 1.97 - 0.91 * U γ = 0.191 / ro2 β = -0.10 + 0.944 / (√( Ep + BG2 )) + (0.069 * ro2 ) λe = 1000 / [ Ep (β × log(γ * 1000) - ( C2 / 1000 ) + (C1 / 10002)) ] Where, λe = Mean Free Path in Copper Aw = Atomic Weight VE = Valence Electrons BG = Bandgap (Copper = 0.0) ro = Density U = Mean Ep = Energy C1, C2 = Radius β, γ = Radio Active Charges
