WebSep 15, 2024 · We study different microscopic scattering mechanisms in Na Sn 2 As 2, and we present the electron-phonon scattering time distribution on its Fermi surface in momentum space, the open concave shape of which is proposed to be the origin of the axis-dependent conduction polarity. Further, we obtain the overall anisotropic lifetime tensors … WebJun 8, 2024 · For an electron in Cu metal at 300 K, the scattering time τ is about 2 x 10 -14 s. From this we can calculate the mean free path as: (6.6.3) λ = v a v g τ ≈ v F τ = ( 1 × 10 6 m / s) ( 2 × 10 − 14) = 40 n m. The mean free path (40 nm = 400 Å) is quite long compared to the interatomic spacing (2 Å). To put it in perspective, if the ...
