Classification: CPC F  H | IPC F

Claim 7:
8. An apparatus comprising:
a printed circuit board;
an integrated circuit package mounted on the printed circuit board;
a heat sink formed from a plurality of graphene layers with carbon nanotubes interposed between the plurality of graphene layers, wherein a first carbon nanotube of the carbon nanotubes is interposed between a first graphene layer of the plurality of graphene layers and a second graphene layer of the plurality of graphene layers, a second carbon nanotube of the carbon nanotubes and a third carbon nanotube of the carbon nanotubes are interposed between the second graphene layer and a third graphene layer of the plurality of graphene layers, and the first carbon nanotube is offset from the second carbon nanotube such that a first portion of the first carbon nanotube is positioned above the second carbon nanotube and a second portion of the first carbon nanotube is positioned above an area between the second carbon nanotube and the third carbon nanotube; and
a frame mounted on the printed circuit board, wherein the heat sink is positioned on the frame and in direct contact with the integrated circuit package through an opening in the frame.
