Exploitable results Diamond for applications in thermal management This programme aimed to assess a number of innovative chemical vapour deposition (CVD) techniques including chemical vapour infiltration to preforms and to assess their potential for producing free standing diamond layers (0.5 mm thick) with a thermal conductivity at least 3 times that of copper at a cost of less than 50 ECU/cm{2}. Free standing diamond samples up to 50 mm diameter have been grown by MPACVD, with thickness up to 1.5 mm. Thermal conductivity of translucent material has been measured as high as 2000 Wm{-1}K{-1}. Diamond thermal management material can be fabricated with either thermal barrier or conducting layers integrated into a single thermal management component. 2 demonstrator devices have been designed using diamond plates as thermal conductors and electrical insulator. The first demonstrator consisted of a high power transister (HPT) currently used in ignition systems as switches. The second demonstrator is a design using an impact avalanche transit time (IMPATT) diode as a velocity sensor. Demonstrators were designed for 3-dimensional packaging of integrated circuits that could be used to make junction temperature measurements. A laser diode was designed which uses existing processes developed for discrete devices. Searching for OpenAIRE data... There was an error trying to search data from OpenAIRE No results available
