Bill, You are right copper oxide is a "Semi-conductor," and it was used in battery chargers 100 years ago, as rectifiers. But whereas I was a bit strong in calling it an insulator, As it passes current in only one direction, I would not call it a very good conductor either. In my experience only gold does not oxidize. However, gold is expensive.
