MEMS fabricated conformal electrodes for thermotunneling cooling

A microelectromechanical system (MEMS) is being developed for controlled fracture of a silicon micro-beam, a promising method for producing a pair of conformal electrodes. The distance between corresponding points in a pair of conformal electrodes remain constant (within a few nm variation) across a large area (~ 1 µm2). This can facilitate large area cold field emission / tunneling, which can be used for many purposes
