Decoding THz‐Driven Dynamic Fingerprints of Ferroelectric Nanotwin Networks

Advanced Materials, EarlyView.
ABSTRACT Ultrafast polarization dynamics in ferroelectrics are of considerable interest for high‐speed tunable dielectrics and electro‐optics. Extended domain wall networks formed in ferroelectric twin nanodomains can support collective dynamics in the terahertz regime but require techniques that track polarization and strain evolution driven by ...

Ultrafast Charge Carrier Dynamics in Layered CuO‐TiO2 Heterostructure via Time‐Resolved Soft X‐Ray Absorption Spectroscopy

Advanced Materials Interfaces, EarlyView.
Ultrafast carriers transfer dynamics in the layered CuO∖TiO2 heterostructure. ABSTRACT Understanding the charge carrier dynamics at the p‐n heterojunctions is indispensable for designing efficient photocatalysts. In this work, we used element‐specific time‐resolved soft X‐ray absorption spectroscopy (tr‐XAS) to investigate the ultrafast charge transfer

Highly Anisotropic Quasi‐Direct Organic Metal Halide Hybrids: A Platform for Polarization‐Sensitive Optoelectronics

Advanced Materials Technologies, EarlyView.
One‐dimensional C4N2H14PbBr4 is shown to have a quasi‐direct electronic band structure and strongly anisotropic transport with polarized broadband emission. A GW/Bethe–Salpeter excited‐state force formalism, supported by polarized Raman and temperature‐dependent photoluminescence, identifies low–frequency Pb–Br phonons that drive ultrafast exciton self‐
