Abstract An insulator-to-metal transition (IMT) is an emergent characteristic of quantum materials. When the IMT occurs in materials with interacting electronic and lattice degrees of freedom, it is often difficult to determine if the energy gap in t

Abstract Room-temperature-superconducting T c measured by high pressure in hydrides can be theoretically explained by a Brinkman–Rice (BR)–Bardeen–Cooper–Schrieffer (BCS) T c combining both the generalized BCS T c and the diverging effective

We investigate transient nanotextured heterogeneity in vanadium dioxide (VO2) thin films during a light-induced insulator-to-metal transition (IMT). Time-resolved scanning near-field optical microscopy (Tr-SNOM) is used to study VO2 across a wide par

The growth of high-quality single crystalline nano- and microwires of VO2 is necessary to study the Mott transition and to expand its applications. Here, we propose a modified vapor-transport method characterized by a one-step process that does not r

Efficient electroreduction of CO2 to multicarbon products is a complicated reaction because of the high energy barriers for CO2 activation and C–C coupling. Here, we design a graphitic frustrated Lewis pair catalyst doped with boron and nitrogen (B
