Abstract:
1. A method of manufacturing a thermal transfer device, comprising: providing first and second thermally conductive substrates that are substantially atomically flat; providing a patterned electrical barrier having a plurality of closed shapes on the first thermally conductive substrate; providing a nanotube catalyst material on the first thermally conductive substrate in a nanotube growth area oriented within each of the plurality of closed shapes of the patterned electrical barrier; orienting the second thermally conductive substrate opposite the first thermally conductive substrate such that the patterned electrical barrier is disposed between the first and second thermally conductive substrates; and providing a precursor gas proximate the nanotube catalyst material to facilitate growth of nanotubes in the nanotube growth areas from the first thermally conductive substrate toward, and limited by, the second thermally conductive substrate, wherein introduction of current flow between the first and second thermally conductive substrates enables heat transfer between the first and second thermally conductive substrates via a flow of electrons between the first and second thermally conductive substrates.
