3D Variable Range Hopping Electrical Conduction of a Carbon from Polyaniline Vapor

Blog Article

Carbon with a metallic reflection was prepared from polyaniline (PANI) vapor deposited on the inner quartz wall of a furnace.Electron probe microanalyzer analysis proved that the resultant contained carbon, oxygen, nitrogen, and sulfur atoms.A Dysonian line shape with Propane Freezer paramagnetic properties was observed for the resulting carbon from PANI in the electron spin-resonance spectroscopy measurement.The resistance vs.temperature curve of the carbon indicated semiconductor-insulator properties in a low-temperature range.

Electrical Basket conduction in the carbon was carried out with 3D variable range hopping.
