Thermal intermediate apparatus, systems, and methods
Apparatus and system, as well as fabrication methods therefor, may include a thermal intermediate structure comprised of a plurality of carbon nanotubes some of which have organic moieties attached thereto to tether the nanotubes to at least one of a die and a heat sink. The organic moieties include thiol linkers and amide linkers.
1. A process:
coating at least one surface of least one of a heat sink and of a die with a metal;
oxidizing carbon nanotubes ropes in sulfuric and nitric acids, whereby the carbon nanotubes ropes are cut into a plurality of short carbon nanotubes with open ends having carboxyl linkages attached thereto;
treating at least one end of at least some of a plurality of carbon nanotubes by applying organic moieties thereto; and
tethering one end of the at least some of the carbon nanotubes of the plurality of carbon nanotubes to the metal.
2. The process of claim 1 wherein the metal is selected from the group consisting of gold and gold alloys.
3. The process of claim 2 , wherein the treating the at least one end of some of the plurality of nanotubes comprises forming an amide based linkage thereon.
4. The process of claim 2 , wherein the treating the at least one end of some of the plurality of nanotubes comprises forming an amide based linkage and a thiol based linkage thereon.
