From this condition, the electron beam energy E e can be detuned to achieve the desired center-of-mass electron–ion collision energy, 28 28. Here, the reduced mass of the electron–ion collision system is well approximated by the electron mass.
WebIons are directed to the substrate with an angular spread due to the ion thermal velocity at the sheath edge. The thermal velocity causes ions to have a velocity component parallel to the substrate surface while the sheath electric field accelerates the ion toward the substrate in the perpendicular direction.
