Hi Joerg, nanometers sounds hard! (But I really don't know.) Is
this thing going to live in vacuum? For optics I always figured the
scratch and digs are in the few micron range. (You've got to be able
to see them after all.)

I know it's hard. That's why I am asking here :)

I think a monolayer of water on your surface will be in the nanometer
range.

Liquids won't work in our case.

A surface monolayer of water isn't a liquid in the usual sense. BET theory (and experimental evidence) says that the individual atoms of the monolayerare bonded to the adsorbing surface more strongly than they are to other water molecules. How good it's electrical conduction is is another question,but it's a real swine to get rid of it. Surface chemists go in for ion bombardment if they want an atomically clean surface.

As I seem to have mentioned before, the "T" in BET is Edward Teller who went on to work on the hydrogen bomb.

What about those black anti-static bags. They stretch and the conductive
coating is built in?


The ones I have encountered have little conductivity and a harsh surface.

But we can't have a mushroom cloud over our lab :)

The wife would disapprove? But who would Tell'er?
