  • SUPERCONDUCTOR TRANSISTOR AND METHOD FOR MANUFACTURING SUCH TRANSISTOR
    Publication number: 20110254053
    Abstract: This field-effect superconductor transistor (2) comprises a source electrode (4) and a drain electrode (6), connected by a superconducting channel (12), the channel (12) and the source (4) and drain (6) electrodes being arranged on a substrate (16), and a gate electrode (8) covering the channel (12). A layer (14) of semiconductor material is arranged between the channel (12) and the gate electrode (8), to control over the critical current of the superconducting channel (12) between a minimum value Ic_min and a maximum value Ic_max, by controlling the surface roughness of said channel (12), said surface roughness being controlled by combining the proximity effect between the superconducting channel (12) and the layer (14) of semiconductor material with the field effect in the layer (14) of semiconductor material by polarising the gate electrode (8).
