Which phenomenon prevents electrons flowing in specific directions through a crystal lattice?

💡 Explanation

Bragg diffraction prevents electron flow because wave interference creates a band gap preventing propagation at certain angles, therefore, electrons cannot flow in specific directions, rather than backscattering or quantum tunneling impeding all current.
