In Reply to: No experience, but some obvious problems: posted by Al Sekela on December 18, 2006 at 11:25:48:
Al,You bring up some interesting issues. Perhaps the least of these issues is outgassing. In a vacuum tube, gas leads to short tube life, among other things. I think in a vauum capacitor it would only lead to a lower voltage rating and maybe a little df. So I would guess that a little outgassing wouldn't be disastrous.
On a second note, it just occured to me that there is the possibility of making a vacuum state integrated circuit. For instance, the grid could have two leads. One for biasing (or grid leaking) and one coupled through an internal vacuum capacitor for signal input.
Thanks for your response.
