- jpmattia 11y agoDoubtful: You can't really dope it n-type. Diamond has the interesting property of having it's conduction band above vacuum level, so that free electrons would (in principle) fall out of the material. (Surface physics gets in the way of that.) It's the reason that diamond is used for cold-cathode emitters btw.
