Invited talk

Artificial electronic crystals provide a route to engineering both band structure and electron interactions in a highly controllable solid-state system [1]. We realise such crystals by imposing a nanoscale periodic electrostatic potential on a high-mobility two-dimensional electron gas in an ultrashallow GaAs quantum well. The strength of the periodic potential can be continuously controlled...

Over the last few decades, topological insulators have emerged as an important class of materials for quantum technologies, offering robust conducting surface states with potential applications in low-energy field-effect transistors and heterogeneous catalysis.$^{1-3}$ Recent studies of two-dimensional (2D) materials known as transition metal dichalcogenides (TMDs) have identified topological...

Climate change has become one of the most pressing environmental challenges worldwide. The carbon dioxide reduction reaction (CO2RR), which converts CO2 into value-added chemicals using renewable energy, is considered a promising strategy for carbon recycling and sustainable energy development. However, the high thermodynamic stability and chemical inertness of CO2 make its adsorption and...

In this work we explore the possibilities of creating an artificially synthesised topological insulator (TI) with a flat-band quasiparticle spectrum for realising new emergent superconductivity physics, either in the form of the unconventional bulk superconductivity [1] or by interfacing the TI with a conventional superconductor. The TI is synthesised using an engineered semiconductor...

The Josephson junction is the fundamental building block of superconducting circuits. Although critically important, its manufacture has proved highly variable, resulting in large distributions of circuit parameters due to the stochastic nature of the deposition process and material disorder. The recent discovery of the alternating bias-assisted annealing method has reintroduced interest in...
