Can flexible substrates be used to grow films in magnetron sputtering systems?

I want to grow thin films (e.g. TiO2) on flexible materials. Which substrates could be used? It should support high temperatures. I guess that the adhesion of the sputtered target is an issue, right?

What does it mean that the semiconductor equations are strongly coupled, preventing the Gummel method to reach the convergence?

Gummel method is hard to converge when the coupling between semiconductor equations (Poisson, continuity of electrons and holes) is strong. In this situation, Newton method is the appropriate...
