This project aims to develop a material with ultrahigh electron mobility and conductivity well above today’s materials at room temperature to enable next generation nanoelectronics. The demand for higher performance and lower power consumption in electronic systems drives the creation of materials for devices in nanometre scale. The success of these materials depends on enhancement in carrier mobility and conductivity. This project will spatially separate the electron generation layer from the conduction layer by individually engineering the atomically sharp complex oxide heterointerfaces to enhance the electron mobility and density. This is expected to develop new materials and nanoelectronic technologies.Read moreRead less

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
