Outstanding photovoltaic (PV) materials combine a set of advantageous properties including
large optical absorption and high charge carrier mobility, facilitated by small effective …

A pair of zero‐dimensional lead‐free chiral perovskites is introduced towards the detection
of circularly polarized light (CPL). Although spin‐polarized carriers are generated in the …

Light engineering of correlated states in topological materials provides a new avenue of
achieving exotic topological phases inaccessible by conventional tuning methods. Here we …

We report terahertz (THz) light-induced second harmonic generation, in superconductors
with inversion symmetry that forbid even-order nonlinearities. The THz second harmonic …

The Higgs mechanism, ie, spontaneous symmetry breaking of the quantum vacuum, is a
cross-disciplinary principle, universal for understanding dark energy, antimatter and …

Direct visualization and quantitative evaluation of charge filling in grain boundary (GB) traps
of hybrid metal halide perovskites require dynamic conductivity imaging simultaneously at …

Inorganic lead halide perovskite nanocrystals (NCs) are an exciting class of luminescent
materials with high defect tolerance and broad spectral tunability, but such NCs are …
