Sheath discussion:
1. (a) When we talked about sheaths, we discussed Bohm velocity. What is Bohm velocity?
(b) Typical electron temperature of process plasmas is Te = 1- 10 eV. Consider Argon plasma. Compute the Bohm velocity when the electron temperatures are 1eV, 3 eV, and 5 eV. Report your answers in m/s
