Chemical Doping Engineering of Polarization and Topological Textures in van der Waals Ferroelectric CuInP2S6

open access: yesAdvanced Science, EarlyView.
Our work reports that Li⁺ doping in CuInP2S₆ induces coexistence of high‐ and low‐polarization states, which fosters a rich spectrum of topological polar textures, such as bubbles and labyrinth domains. An unconventional flexoelectric effect is also discovered, where strain gradients can mechanically manipulate these polarization states and their ...

Large‐Scale Synthesis of Monodispersed Perovskite Nanocrystals via Autonomous Continuous Droplet Microfluidics

open access: yesAdvanced Science, EarlyView.
In this work, we propose a novel on‐chip microscale continuous droplet‐in‐flow synthesis (μ‐CDFS) that utilizes zwitterionic ligands to enable large‐scale preparation of perovskite nanocrystals (PNCs) with high emission efficiency and monodispersity.

Halogen‐Bond Coupled Halogenated‐π‐Conjugation Enables Giant Birefringence in Hydrogen‐Bonded Organic Frameworks

open access: yesAdvanced Science, EarlyView.
The perfect crystal packing achieved via the halogen‐bond (XB) coupled halogenated‐π‐conjugation strategy effectively induces an ultrahigh birefringence (Δn = 0.97), which exhibits promising potential in polarization control and phase modulation.
