# Mean Free Path of Electrons Calculator

The mean free paths for inelastic electron diffusing in Silicon have been measured using off-axis electron holography in a field-discharge transmission electron magnifying lens. In this calculator, you can obtain the mean free path in Silicon [Si] from the known atomic weight, valence electrons and density.

Code to add this calci to your website  #### 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 Silicon Aw = Atomic Weight VE = Valence Electrons ro = Density BG = Bandgap U = Mean Ep = Energy C1, C2 = Radius β, γ = Radio Active Charges
