This project aims to provide a viable solution for heat management in microelectronics by using highly efficient Peltier devices made with thin combinatorial films. Heat generated by electric current, which is ubiquitous in microelectronic devices, has become increasingly problematic for high density charge-based logical circuitries. The project will significantly enhance the energy conversion efficiency of Peltier devices by optimising the interdependent electron and phonon transports, simultaneously, with a new concept of thin combinatorial films for heat management in microelectronic devices. This is expected to facilitate the development of novel materials in Australia, with access to a large global market.Read moreRead less
