摘要： A composite thermal interface material and methods are shown. Devices such as lithium ion batteries incorporating composite thermal interface materials show significant improvement in cooling performance. In one example, composite thermal interface materials shown provide cooling through both a phase change mechanism, and a heat conducting mechanism which directs heat away from the device to be cooled, such as electrochemical cells in a battery, to an external housing and/or a coupled heat exchange device such as radiating fins.

摘要： A dual-gate transistor having a negative differential resistance (NDR) region is disclosed. The dual-gate transistor includes a back-gate, a zero-bandgap graphene layer disposed on the back-gate, a top-gate disposed on a portion of the zero-bandgap graphene layer adjacent to the top-gate, and a drain disposed on a portion of the zero-bandgap graphene layer adjacent to the top-gate and displaced from the source. Also included is a dynamic bias controller configured to simultaneously sweep a source-drain voltage and a top-gate voltage across a Dirac point to provide operation within the NDR region. Operation within the NDR region is employed to realize non-Boolean logic functions. Graphene-based non-Boolean logic circuits are constructed from pluralities of the disclosed dual-gate transistor. Pattern recognition circuitry for operation between 100 GHz and 500 GHz is also disclosed via the graphene-based non-Boolean logic circuits.
