Polymorphic 2D materials allow structural and electronic phase engineering, which can be
used to realize energy-efficient, cost-effective, and scalable device applications. The phase …

Resonant inelastic X-ray scattering (RIXS) is a powerful technique that combines
spectroscopy and inelastic scattering to probe the electronic structure of materials. RIXS is …

Space charge transfer is crucial for an efficient electrocatalytic process, especially for narrow-
band-gap metal sulfides/selenides. Herein, we designed and synthesized a core–shell …

Understanding quantum materials—solids in which interactions among constituent electrons
yield a great variety of novel emergent quantum phenomena—is a forefront challenge in …

Single-photon emitters serve as building blocks for many emerging concepts in quantum
photonics. The recent identification of bright, tunable and stable emitters in hexagonal boron …

The principal purpose of this topical review is to single out some of the universal features of
high-temperature (high-T c) and related strongly-correlated systems, which can be …

Enormous enhancement of superconducting pairing temperature (T g) to 65 K in
FeSe/SrTiO3 has made it a spotlight. Despite the effort of interfacial engineering, FeSe …

Collective spin excitations in magnetically ordered crystals, called magnons or spin waves,
can serve as carriers in novel spintronic devices with ultralow energy consumption. The …

The origin of the electronic nematicity in FeSe is one of the most important unresolved
puzzles in the study of iron-based superconductors. In both spin-and orbital-nematic models …

Unraveling the magnetic order in iron chalcogenides and pnictides at atomic scale is pivotal
for understanding their unconventional superconducting pairing mechanism, but is …
