Chiral Phase Change Nanomaterials
Advanced Functional Materials, EarlyView.This work demonstrates reversible, non‐volatile phase transitions in chiral Ge2${\rm Ge}_2$Sb2${\rm Sb}_2$Te5${\rm Te}_5$ (GST) nanohelices for high‐speed optical modulation of chirality and dynamic control of the state of polarization (SOP). The chiral nanostructures are fabricated using a highly directional, wafer‐scale physical vapor deposition ...

Advanced Functional Materials, EarlyView.Contrary to conventional expectations, the bulk photovoltaic effect in CuCrP2S6 is enhanced rather than suppressed upon transitioning into the crystallographically centrosymmetric phase. Dynamic Cu‐ion disorder creates transient polar states, which substantially amplifies zero‐bias photocurrent (shift‐current) generation, establishing dynamic symmetry ...
