| Description | Novel Thermal Management of Power Electronic Devices The work done in this grant has two principal research impacts: the improved understanding of Gunn device power management and the key importance of hetero-structure design in electro-thermal coolers. Gunn diodes are power hungry devices consuming large amounts of electrical energy and producing great amounts of heat energy. It is of key importance to understand the complex interplay between contact design, impact ionization and consequent electro-luminescence in these devices. Five journal publications have resulted from this work in which each of these key issues is explored in detail along with commensurate improvements in device frequency from these devices. With respect to the work on electro-thermal cooling technology, two journal publications detailing the crucial importance of the correct hetero-structure design highlight the importance of this issue in future development of such devices. The sensitivity to small alterations to the interface will have a direct impact on all workers attempting to fabricate these devices and will influence devices design and modelling. .
