The hetero-interface is the device: a computational approach

Designing hetero-interfaces towards new optoelectronic functionalities using large-scale computations Assembling ‘Lego-like’ 2D ‘heterostructures’ can give rise to emergent properties and functionalities very different from the intrinsic characteristics of the constituents. Density functional theory (DFT)-based band-structure calculations can shed light on interfacial properties of different heterostructures. Interface properties of 2D perovskite/TMD heterostructures Heterostructures based on different 2D materials have resulted in …

Brilliant alternative uses for diamond showcased in concept jewellery

QUT/FLEET researcher A/Prof Dongchen Qi has joined forces with an Australian jewellery designer to showcase the brilliance of diamond in medical, scientific, and other applications. Diamond does not naturally conduct electricity, but Professor Qi, from the QUT Centre of Material Science, led research to make it both conductive and controllable as a high-capacity semiconductor. Semiconductors conduct or insulate electrical signals …

Topological superconductors: fertile ground for elusive Majorana particle

Majorana fermions promise information technology with zero resistance A new, multi-node FLEET review investigates the search for Majorana fermions in iron-based superconductors. The elusive Majorana fermion, or ‘angel particle’ proposed by Ettore Majorana in 1937, simultaneously behaves like a particle and an antiparticle – and surprisingly remains stable rather than being self-destructive. Majorana fermions promise information and communications technology with …
