I took the original question to be looking for effects like adding carriers to semiconductors; I don't expect any such effects here since conductors already have lots of carriers. In theory they might form Cooper pairs or something (which is what superconductors have) but I don't see why they would. | |

These additional electrons are not neutralized, therefore you can not assume that their contribution is the same as of the conduction electrons in a neutral conductor. | |
