FLEET addresses a grand challenge: reducing the energy used in information technology, which now accounts for 8% of the electricity use on Earth and is doubling every 10 years.
The current, silicon-based technology will stop becoming more efficient in the next decade as Moore’s law comes to an end.
FLEET will meet this challenge by realising new types of electronic conduction without resistance in solid-state systems at room temperature. These concepts will form the basis of new types of switching devices (transistors) with vastly lower energy consumption per computation than silicon CMOS. Electronic conduction without resistance will be realised in topological insulators that conduct only along their edges, and in semiconductors that support superflow of electrons strongly coupled to photons. These pathways are enabled by the new science of atomically thin materials.
RMIT University leads Fleet Enabling Technology B — Nano-Device Fabrication. Researchers in this theme focuses on realising novel high temperature quantum anomalous Hall systems in Research Theme 1. They utilise two techniques, exfoliating bulk single crystal and CVD synthesis of nanostructures, to synthesise novel 2D materials in Enabling Technologies Theme A.
Specialised techniques are needed to integrate novel atomically thin materials into high-quality device structures with suitable performance. For example, atomically thin topological insulators will need to be integrated with electrical gates to realise topological transistors, and atomically thin semiconductors must be integrated with optical cavities to realise exciton-polariton condensate devices.
