Tailoring electron transfer dynamics across solid–liquid interfaces is fundamental to the interconversion of electrical and chemical energy. Stacking atomically thin layers with a very small azimuthal misorientation to produce moiré superlattices enables the controlled engineering of electronic band structures and the formation of extremely flat electronic bands. Here, we report a strong twist angle dependence of heterogeneous charge transfer kinetics at twisted bilayer graphene electrodes with…

Heterogeneous electrocatalysis goes chemical

Despite over a century of research to understand heterogeneous electrocatalysis, the precise mechanisms of action remain poorly understood. Now, it is proposed that the oxygen evolution reaction on

Strain fields in twisted bilayer graphene

These results establish the reconstruction mechanics underpinning the twist-angle-dependent electronic behaviour of twisted bilayer graphene and provide a framework for directly visualizing structural relaxation, disorder and strain in moiré materials.

Marcus-Hush-Chidsey kinetics at electrode-electrolyte interfaces.

This work explicitly account for the density functional theory-calculated density of states numerically in calculating electrochemical reaction rates for a variety of electrode-electrolyte interfaces and identifies the asymmetry in reaction rates as a function of discharge/charge naturally within this approach.

Electronic-structure methods for twisted moiré layers

When single layers of 2D materials are stacked on top of one another with a small twist in orientation, the resulting structure often involves incommensurate moiré patterns. In these patterns, the

Correlated electronic phases in twisted bilayer transition metal dichalcogenides

The observation of tunable collective phases in a simple band, which hosts only two holes per unit cell at full filling, establishes twisted bilayer transition metal dichalcogenides as an ideal platform to study correlated physics in two dimensions on a triangular lattice.

Superconductivity and strong correlations in moiré flat bands

Strongly correlated systems can give rise to spectacular phenomenology, from high-temperature superconductivity to the emergence of states of matter characterized by long-range quantum entanglement.

Visualization of the flat electronic band in twisted bilayer graphene near the magic angle twist

Bilayer graphene was theorized to host a moire miniband with flat dispersion if the layers are stacked at specific twist angles known as the magic angles. Recently, such twisted bilayer graphene
