Electrical Resistivity of Fe‐C Alloy at High Pressure

We measured the electrical resistivity of iron, Fe 99 C 1, Fe 3 C, and Fe 7 C 3 up to ~80 GPa using the van der Pauw method in a diamond anvil cell. The electrical resistivity of disordered Fe 99 C 1 at high pressure shows a strong impurity resistivity of carbon. The ferromagnetic‐paramagnetic transition in Fe 3 C and Fe 7 C 3 is associated with the flattening of the resistivity pressure

FAQs - Frequently Asked Questions about Silicon …

Silicon carbide, in its pure form, behaves as an electrical insulator. However, with the controlled addition of impurities or doping agents, and because SiC has the necessary resistivity, it can express semi-conduction properties; in other words, as a semiconductor, it neither allows a free-flowing current nor completely repels it.
