The research group was established by
Prof. WJ Perold after a sabbatical at Hirst Research Centre in Wembley, London, in 1988.
At present research in the Department of Electrical and Electronic Engineering is focused
on the following aspects of superconductivity:
 | Ultra-high speed voltage-state Josephson logic circuits |
| Rapid Single Flux Quantum (RSFQ) logic cicruits |
| On-chip superconducting amplifier circuits to interface to room temperature
semiconductor circuits |
| High-temperature superconductor SQUID magnetometers and the accompanying linearization
circuits such as flux-locked loops. |
| High-temperature superconductor passive circuits such as narrowband filters |
Fabrication and testing facilities include:
| Laser ablation facilities at the Department of Physics for the deposition of high
quality high- temperature superconductor thin films |
| Computer controlled cryocooler down to 10K for the evaluation of parameters such as the
critical temperature of thin films |
| Access to extensive surface evaluation techniques such as Rutherford backscattering
(RBS) and atomic force microscopy (AFM) |
| Mask making and etching facilities |
