Abstract
We obtain electron and hole mobilities from the measured Hall mobility of (TMTSF)2 PF6. At 4K these are greater than 106cm2/Vsec and agree with the mobility calculated for acoustic phonon scattering. The initial increase of conductivity in dc fields found at low temperatures in this material can be accounted for by single particle effects, specifically heating of the carriers by the field. To explain further increases we suggest that the gap is spatially nonuniform. This could be accounted for by dislocations.
