Electromagnetic pulse for intermittent but high load operations (such as emission of a modulated RF signal), thermopower wave propagation, energy storage, thermally-triggered electromagnetic pulse.
This invention describes the generation of a high power electrical pulse from sub-mm3 devices. A carbon nano-tube, a high aspect-ratio molecule with a large phonon thermal conductivity, is used to launch a thermopower wave along its length, which provides a useable power pulse from a sub-micron scale component. The invention is implemented with an annular coating of a reactive, high energy chemical around a carbon nano-tube or nano-wire, or by depositing a thin layer on a graphene sheet. Upon decomposition of the energetic chemical, its heat of reaction funnels into the thermal conduit where the thermal wave propagates much faster than the bulk reaction. The directed wave pushes an accompanying electron wave that generates sizeable thermopower for a device of its size.
Demonstration of the first application of carbon nano-tubes (CNTs) as thermal conduits to generate 1-D energy release with fast reaction velocity and a thermoelectric wave.
