Thickness‐Tuned Berry Curvature in vdW Epitaxial Cr3Te4 Ultrathin Films

open access: yesAdvanced Electronic Materials, EarlyView.
An investigation of thickness‐modulated Berry curvature in stoichiometric, high‐quality van der Waals epitaxial Cr3Te4 films. Surface and interface Te(CrTe2)‐termination enables Fermi level shifting via thickness variation, modulating Berry curvature near the band crossing point, thereby establishing termination engineering (may called Terminonics) as ...

Multiscale Perspectives on Perovskite Instability: From Atomistic Deformation to Device Degradation in Perovskite Solar Cells

open access: yesAdvanced Energy Materials, EarlyView.
Multiscale perspectives on how excess charges in soft lead halide perovskites induce operational instability in photovoltaic devices are presented. Localized carriers formed under thermodynamic non‐equilibrium states modify atomistic interactions and drive lattice distortions, accelerating device degradation.

Chiral Molecular Configuration‐Mediated Crystallization of Perovskites for High‐Performance Solar Cells

open access: yesAdvanced Energy Materials, EarlyView.
In this work, we propose a chiral stereo‐anchoring strategy to modulate the colloidal evolution and crystallization behavior of FAPbI3 perovskites via stereochemical molecular design, which effectively regulates nucleation kinetics and promotes ordered crystal growth.
