Volatile eutectics to tailor crystallization for perovskite optoelectronics

Improvements to the radiative efficiency of halide perovskite thin films are necessary to approach fundamental solar cell performance limits. We tailored perovskite crystallization by leveraging the eutectic interaction between zinc bromide and methylammonium chloride additives....

Integration of high-κ oxide on 2D semiconductors with carbon-dot monolayer assembly as van der Waals interfacial layer

The atomically smooth surfaces of two-dimensional (2D) nanomaterials minimise scattering-induced carrier-transport degradation. However, this same attribute poses a major challenge for integrating 2D materials with high-quality dielectrics at sub-nanometre equivalent oxide thickn...

Field-driven hybrid filament formation governs switching in Ta–HfO2–Pt memristors

Memristive devices have gained significant attention for their potential in next-generation non-volatile memory and neuromorphic computing architectures. Among emerging candidates, transition metal oxides have proven particularly promising. While the switching mechanism in Ta/HfO...
