Atomic‐Scale Insights Into Antisite‐Defect‐Induced Metallicity in Halide Perovskites

Small, Volume 22, Issue 14, 6 March 2026.
Using an aberration‐corrected scanning transmission electron microscope, we identify that the PbCs antisite defect in CsPbBr3 shortens the Pb─Pb bond by ∼20 pm, and induces local strain and polarization, leading to a semiconductor‐to‐metal transition.

Flexoelectricity in nematic domain walls

Physical Review E, 2008
Flexoelectric effects are studied in the domain walls of a nematic liquid crystal device showing the Freedericksz transition. Walls parallel to the alignment direction have a strong twist distortion and an electro-optic effect dominated by e1-e3 is seen.
