Whats your process for surface passivation?

G. K. Waruni Perera

Imalka Jayawardena Bubbling of solvents

Imalka Jayawardena Is it due to energy band alignment mismatches??

It could be that the solvent bubbling restructures to a point where it’s either too defective, or the defects formed are not passivated by the molecules you are using. Have you tested if the Vic drops just because of the solvent alone?
