Unless otherwise stated, resistivities are taken from Kaye & Laby Tables of Physical & Chemical Constants[6] while temperature coefficients ((1/ρ) dρ/dT) are taken from Smithells Metals Reference Book.[7]
Notes
- ↑ 1.0 1.1 1.2 Resistivity and conductivity quoted for 300 K (27 °C).
- ↑ The bulk isotropic resistivity and conductivity is given for amorphous graphitic carbon; the anisotropic resistivities are given for pyrolytic graphite.
- ↑ 3.0 3.1 3.2 3.3 The resistivities and conductivities of semiconductors are extremely sensitive to sample purity.
- ↑ 4.0 4.1 Resistivity and conductivity quoted for 373 K (100 °C).
- ↑ The temperature of macroscopic samples of polonium can only be approximately measured and controlled because of substantial radioactive self-heating.
