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
Beyond the Ferroelectric Field Effect Transistors. The von Neumann paradigm is the foundation of modern computing systems, which are based on the data exchange between central processing unit (CPU) and memory. The physical separation between the CPU and memory will cause von Neumann bottleneck – a memory wall to limit the data processing speed for contextually intelligent applications.

The von Neumann paradigm is the foundation of modern computing systems, which are based on the data exchange between central processing unit (CPU) and memory. The physical separation between the CPU and memory will cause von Neumann bottleneck – a memory wall to limit the data processing speed for contextually intelligent applications. This project aims to develop a novel ferroelectric field effect transistor that integrates a ferroelectric material into a semiconductor transistor structure to merge logic and memory functionalities in a single-device level. This will solve the memory wall problem while provide low power, high speed, high density and long data retention time for future logic-in-memory and data centric computing paradigms.Read moreRead less
