✦ Synopsis

An analysis has been made of experimental results of the pressure-dependence of the conductivity taking into account recent work on the evaluation of pressure derivatives of the band parameters (d In -y,/dp) which are sensitive to the band model chosen and assumptions used to interrelate the derivatives. The pressure-dependence of the conductivity of pyrolytic graphite at low temperature is analyzed in detail, including the influence of the band overlap parameter y3 and effects related to carrier non-degeneracy, which are shown to be very important in analyzing experimental results.
