Notes

  1. 1.0 1.1 1.2 Resistivity and conductivity quoted for 300 K (27 °C).
  2. The bulk isotropic resistivity and conductivity is given for amorphous graphitic carbon; the anisotropic resistivities are given for pyrolytic graphite.
  3. 3.0 3.1 3.2 3.3 The resistivities and conductivities of semiconductors are extremely sensitive to sample purity.
  4. The isotropic resistivity and temperature coefficient are given for liquid mercury at 0 °C; the anisotropic resistivity is given for crystalline mercury at 227.7 K (−45.5 °C).
  5. 5.0 5.1 Resistivity and conductivity quoted for 373 K (100 °C).
  6. The temperature of macroscopic samples of polonium can only be approximately measured and controlled because of substantial radioactive self-heating.
