High Performance Graphene Infrared Heater Graphene is an atom thick layer made of carbon atoms that are arranged in an hexagonal lattice. It is the most efficient thermal conductor at temperatures of room temperature (thermal conductivity 5300 W*m-1*K-1) and is the most well-known conductor of electricity (studies reveal electron mobility that is greater than 15,000 cm2*V-1*s-1) and is transparent to light (with light absorption of 2.3 3 % white light, or 97.7 percent transmission).
