Emerging device technologies

The research group 

The Emerging Device Technology (EDT) Research Group is composed of researchers whose interests are based around the theme of materials and devices in general. There is a solid research base with its staff having many years experience in superconducting, insulating and semiconducting materials. The research includes the basic science of materials, characterisation and the production of materials for specific applications. The demonstration of applications in collaboration with end users forms a significant part of the groups work. The scope of this potentially wide area of research is determined by our choice of materials to be investigated, which is governed by the extensive knowledge in the group for the requirements of modern technology. 

The research 

The EDT group has developed out of a strong research programme on superconducting, ferroelectric, ferrite, dielectric and semiconducting materials as well as the development of new micromachining technology. In many cases the study of these materials has been directed towards final applications in the microwave and RF area with research on microwave measurements, microwave passive circuits, antennas, and metamaterials while in other cases the research has concentrated on the fundamental properties of materials and devices. Micromachining technology for terahertz circuits is an important area for the group.

The group is now very multi-disciplinary in nature, and a large class 10,000 clean room facility (54m2) enables the production of a number of materials for application in microwave circuits. In addition to the sputtering of high quality superconductors, the centre produces ferroelectric, dielectric and metal thin films for research.

These materials are optimised for use in a number of microwave circuits including tuneable filters, duplexers, delay lines, antennas and other passive signal processing circuits. This work has lead to the publication of a book on microwave filters [2] as well as several patent applications. There is also work on a number of novel microwave structures using micromachining techniques for application in the frequency range 1-110GHz.

In addition to device work the centre has been working on a superconductor receiver system for mobile communication base stations with a number of European collaborators. The system has been tested in Portugal by the operator TMN with considerable success.
