Electronic devices based on Single Electron Tunneling (SET)

Future electronics is expected to be based on quantum mechanical tunneling of single electrons and/or Cooper pairs (SET and/or CPT) in extremely small structures (mesoscopic or nanostructures). The simplest three-terminal device is the SET transistor. The project includes experimental and theoretical studies of the noise and nonlinear properties of SET devices. The experiments require very careful electrical shielding and millikelvin tempertures. In metrology the SET devices have future applications as current standards and extremely sensitive electrometers.
