Abstract

1,023,509. Super-conductor devices. MULLARD Ltd. Oct. 15, 1964 [Oct. 25, 1963], No. 42218/63. Heading H1K. A super-conductor device comprises two electrodes between which are a plurality of tunnelling regions formed by insulating material lying between islands of super-conductor material and means for applying a magnetic field to control the phase of the super-conductor material; the arrangement provides a first value of impedance when the super-conductor material is normal and a higher value when it is super-conductive. Fig. 6 shows a cryotron comprising a gate conductor 3 separated by a silicon monoxide layer 4 from super-conductor ground plane 2 of lead on a quartz glass substrate 1. The control conductor consists of a lead strip 5separated by a silicon monoxide layer (not shown) from gate conductor 3 and a silicon monoxide layer may cover the control conductor. The gate conductor consists of a plurality of islands of tin separated by gaps of 100 Šand may be produced as described in Specification 1,023,519. When the tin is in its normal state, tunnelling by electrons takes place through the gaps and the layer provides a finite impedance; when the tin is superconductive, tunnelling is not possible (unless the applied voltage exceeds a certain minimum value) and the layer presents infinite impedance. The device may be used to match the low impedance of a superconductor computer store, which is connected to the control conductor, to the high impedance of a sense amplifier connected to the gate conductor.
