Two‐Stage Bipolaron Formation in Molecularly Doped Conjugated Polymers

open access: yesAdvanced Materials, EarlyView.
This work investigates bipolaron formation in 2,3,5,6‐tetrafluoro‐7,7,8,8‐tetracyanoquinodimethane (F4TCNQ)‐doped conjugated polymer P(g32T‐T) films with glycol sidechains at two stages of both low and high doping levels. At the early stage, bipolarons mainly form from double doping, enhancing structural ordering, and carrier transport.

Halogen‐Bonded Liquid Crystal Elastomers as Initiator‐Free Photochemical Actuators

open access: yesAdvanced Materials, EarlyView.
The combination of dynamic disulfide bonds and halogen bonds in chain‐extended liquid crystal elastomers enables the fabrication of photochemical actuators without the need for a photoinitiator, advancing the design of multimodal soft actuators that can be reprogrammed and reprocessed through supramolecular functionalization.

Revealing the Altermagnetism in Hematite via XMCD Imaging and Anomalous Hall Electrical Transport

open access: yesAdvanced Materials, EarlyView.
This study combines X‐ray magnetic imaging and electrical transport to uncover the anomalous Hall effect in hematite, an insulating oxide exhibiting unconventional altermagnetic properties. Imaging reveals distinct magnetic domains linked to crystal symmetry, and angular‐dependent transport measurements highlight unusual symmetry‐driven conductivity ...

Industry‐Compatible Fully Laminated Perovskite‐CIGS Tandem Solar Cells with Co‐Evaporated Perovskite

open access: yesAdvanced Materials, EarlyView.
In this work, a highly efficient bilayer methylammonium lead iodide perovskite is fabricated using a scalable co‐evaporation technique. This strategy enhances the film's stability, allowing the deposition of a tin oxide buffer layer via atomic layer deposition without damaging the perovskite.

Monolithic Terahertz Topological Mach‐Zehnder Interferometer

open access: yesAdvanced Materials, EarlyView.
A monolithic topological Mach‐Zehnder interferometer (MZI) is presented, integrating the splitter, combiner, and waveguide arms on a single chip. The interferometric fringes exhibiting high on‐off contrast with extinction ratios over 20 dB are achieved by utilizing tailored unit cells that facilitate interface‐dependent out‐of‐plane radiation losses ...
