Abstract:
1. A cooling device comprising: a channel comprising a first surface and a second surface separated by a gap; a first plurality of diamond nanowires grown on said first surface wherein one of said first plurality of diamond nanowires conducts heat energy from said first surface and dissipates said heat energy into a liquid that is in direct contact with said first plurality of nanowires and wherein one of said first plurality of diamond nanowires contacts said second surface, thereby bridging said gap; and a second plurality of diamond nanowires grown on said second surface wherein one of said second plurality of diamond nanowires conducts heat energy from said second surface and dissipates said heat energy into said liquid and wherein one of said second plurality of diamond nanowires contacts said first surface, thereby bridging said gap wherein a diamond nanowire in contact with both said first and second surfaces comprises a first portion doped with p-type dopant and a second portion doped with n-type dopant to form a p-n junction in said diamond nanowire, wherein application of an electrical current to said diamond nanowire induces thermoelectric cooling of said diamond nanowire.
