The Rice lab of theoretical physicist Boris Yakobson found that putting a cone-like “chimney” between the graphene and nanotube all but eliminates a barrier that blocks heat from escaping.
The research appears in the American Chemical Society’s Journal of Physical Chemistry C.
Heat is transferred through phonons, quasiparticle waves that also transmit sound. The Rice theory offers a strategy to channel damaging heat away from next-generation nano-electronics. [Read more…] about Nano-chimneys can cool circuits, say Rice University scientists
