RESISTIVITY AND HALL-EFFECT OF THE STAGE-1 CDCL2 GRAPHITE-INTERCALATION COMPOUND

The resistivity and Hall effect of the stage-1 CdCl2 graphite intercal ation compound were investigated in the temperature range between 4 an d 300 K with the current parallel or perpendicular to the c axis. The resistivity for both directions is of the form rho(0)+AT+BT2 that resu lts from; electron-phonon scattering. The anisotropy of the resistivit y is of the order of 10(3) and is explained by the undulating cylindri cal Fermi surface of the compound. The Hall coefficient is independent of temperature to within the experimental uncertainty and has a value of 7.0X10(-9) m(3)C(-1) from a net carrier density of 8.9 X 10(26) m( -3).
