Re: Flat conductors (was I need help).

A semiconductor implies a band gap. Since carbon (graphite) hasz a
negative exponential thermal coeffic ient of resistance, it is a
semiconductor; besides the web told me so.

After looking at the table of conductivities I see 0.45 ohm*m
for Ge, at room temperature. For Pasco paper it is 0.32 ohm*m.
Perhaps we should refer to this material as a semiconductor.
