Semiconductor

Any substance that conducts electricity more slowly than a conductor. Semiconductors are common in products like computer chips and, as such, may be traded as commodities. Silicon and germanium are both semiconductors.

In particular, we assume here that such kind of mechanism of doping enhanced [T.sub.c] may be much better pronounced in the case of semiconducting SWCNTs, which may have higher DOS due to lower energy of the Van Hove singularities.
