Effect of Post-treatment on Electrical Properties of Amorphous Hydrogenated Carbon Films Deposited by Gridless Ion Beam Deposition

Abstract

The equilibrium and stability of MARFEs are considered. It is demonstrated that important aspects of the two dimensional problem can be illustrated by a one dimensional treatment. A stability analysis indicates that MARFE formation requires low temperature, high impurity content and low cross-field transport. Additionally, MARFEs tend to form on flux surfaces that contain an X point. It is observed that the transition to a MARFE-like solution can result from a fluctuation induced jump from a neighbouring constant temperature solution.
