Fabrication of suspended single-electron transistors

We have fabricated and measured a novel type of super-conducting single-electron transistor in which the island is not in physical contact with the substrate: the island in fact is suspended above the SiN2-on-Si chip. As a result, the noise coming from fluctuators in the substrate is eliminated. We have demonstrated that the devices fabricated with our method are robust and they display all the functionality associated with standard (non-suspended) single-electron transistors. This circuit element could have applications in quantum computing and nanoelectromechanics.
