Description of the thesis topic
High-power electronic devices, such as supercomputers, generate considerable heat. If this heat is not transferred away from the device's internal circuitry, the circuits will overheat, significantly reducing the lifetime of the device, causing faults and total device failure. Thermal management materials featured by tailored thermal properties are used to dissipate heat away from device circuitry. However, current substrate materials are restricted by their properties and/or high cost of manufacturing.
This project will explore the feasibility to cost-effectively produce a copper/diamond composite with a high thermal conductivity by using 3D printing technology.
The candidate will be in charge of the development of copper/diamond composite materials by selective laser melting. He/she will have to optimize the interfacial zone of the composite material (use of Cu alloy and/or functionalization of the reinforcement). Model materials, fabricated by PVD, will also be studied in parallel. After development, the materials will be characterized in terms of microstructure, chemistry and thermal properties.
The research aims at both advancing fundamental understanding of 3D-printed copper matrix composites and the development of improved manufacturing technologies via interface engineering.
Founded in 1995, the lnstitute for Condensed Matter Chemistry of Bordeaux activities include both fundamental and applied research and focus on 3 domains : Solid State Chemistry, Materials Science and Molecular Science. ICMCB has extensive expertise in design, synthesis, shaping and characterisation of materials, with the goal to explore and optimise their functionalities. This wide scope and a large, complementary spectrum of methods available, generate fruitful synergies among our faculty (researchers, engineers and technical staff) - contributing to the outstanding reputation of the ICMCB.
