Webthe HOPG tube (provided by Optigraph GmbH) is made of rolled HOPG layers stacked concentrically. The in plane and c-axis thermal conductivity of perfect HOPG is less than 10 andabove3000Wm −1K atroomtemperature,respectively. Nonetheless, the thermal conductivity decreases by raising the temperature due to lattice phonon scattering. … http://www.optigraph.eu/references.html
