Electrically-controlled near-field radiative thermal …
N2 - In this work, we propose a hybrid near-field radiative thermal modulator made of two graphene-covered silicon carbide (SiC) plates separated by a nanometer vacuum gap. The near-field photon tunneling between the emitter and receiver is modulated by changing graphene chemical potentials with symmetrically or asymmetrically applied voltage biases.
‘Very nice’ graphene grown on silicon carbide
Researchers at Georgia Tech have discovered a technique for growing what they describe as “high quality” graphene on the surface if silicon carbide wafers. Almost perfect graphene can be flaked from the surface of natural graphite, but researcher are struggling to grow anything approaching that quality on a substrate by methods compatible with chip making.
