Reliable and efficient continuous-wave (CW) lasers have been intensively pursued in the
field of optoelectronic integrated circuits. Metal perovskites have emerged as promising gain …

Metal halide perovskites (MHPs) are characterized as strongly anharmonic and dynamic
lattices. While there is a consensus on the solvation-like polarization effect in these …

Thermally-induced tensile strain that remains in perovskite films following annealing results
in increased ion migration and is a known factor in the instability of these materials …

Single crystals represent a benchmark for understanding the bulk properties of halide
perovskites. We have indeed studied the dielectric function of lead bromide perovskite …

A detailed picture of temperature dependent behavior of CsxFA1-xPbI3 perovskite quantum
dots across the composition range is constructed by performing in situ optical spectroscopic …

Polycrystalline perovskite films offer promise for next-generation X-ray flat-panel detectors
due to their ease of large-area fabrication. However, the perovskite–thin-film transistor (TFT) …

Aside from photovoltaics, metal-halide perovskite semiconductors have also emerged as an
attractive platform for LEDs and even lasers. For all of them, performance and operational …

To fabricate stable neat FAPbI3 perovskite with a pure α‐phase (pure α‐FAPbI3) is important
in the field of photovoltaic commercialization because of its better bandgap than its alloying …

Mixed halide perovskites that are thermodynamically stable in the dark demix under
illumination. This is problematic for their application in solar cells. We present a unified …

Perovskite solar cells (pero-SCs) have undergone rapid development in the past decade.
However, there is still a lack of systematic studies investigating whether the empirical rules …
