Transition metal oxide electrodes are promising for rechargeable batteries but are subject to suffer from structural transformations and electrochemical degradation. The evolution of oxygen-redox activity and reversibility in layered electrodes are shown to arise from cation-migration mechanisms during de/intercalation.

Understanding complex materials at different length scales requires reliably accounting for van der Waals (vdW) interactions, which stem from long-range electronic correlations. While the important role of many-body vdW interactions has been extensively documented for the stability of materials, muc…

A heterostructure supports the equilibrium bound states of an electron and hole—excitons—that strongly interact with each other. This provides a platform for the quantum simulation of bosonic lattice models.

The electronic structure of an electrode can affect the electron transfer rate of electrochemical processes at its surface. Now, it has been shown that varying the ‘twist’ angle between two stacked layers of graphene modifies the bilayer electronic structure and provides a new dimension to control interfacial redox activity.

Ultra-scaled transistors based on two-dimensional MoS2 with physical gate lengths of 0.34 nm are reported, which show relatively good electrical characteristics and can be switched off.

We develop the theory of anomalous elasticity in two-dimensional flexible materials with orthorhombic crystal symmetry. Remarkably, in the universal region, where characteristic length scales are larger than the rather small Ginzburg scale ∼10  nm, these materials possess an infinite set of flat pha…
