I put this question to all of you yesterday, but unfortunately the
temperature was ten times to high. Here is the correct version:
I have experienced a roughening of the single crystalline quartz surface
when cleaning the sample in 80 C concentrated nitric acid. Have you seen
the same thing, or have you some references to HNO3 crystalline quartz
cleaning?
Answers and hints on this subject would be most appreciated,
