Reactivity‐Guided Janus Graphene With Asymmetric Interfacial Electrostatics for Tunable Charge Transport

Advanced Materials, EarlyView.
Stepwise dual‐side functionalization creates covalent Janus graphene with chemically and electrostatically asymmetric interfaces. The resulting nonadditive surface‐potential response and pronounced charge‐transport modulation demonstrate a versatile route for tailoring the electronic properties of graphene.

Combined scanning probe electronic and thermal characterization of an indium arsenide nanowire

Beilstein Journal of Nanotechnology, 2018
As electronic devices are downsized, physical processes at the interface to electrodes may dominate and limit device performance. A crucial step towards device optimization is being able to separate such contact effects from intrinsic device properties ...

Dual Single Atoms Boosting Photocatalytic Upcycling of Raw Polyvinylidene Fluoride Plastic

Advanced Materials, EarlyView.
To resolve the catastrophic disaster of plastic contamination, the Cu‐Fe dual‐single‐atom‐loaded In2P3S9 NSs photocatalyst was prepared for direct conversion of raw polyvinylidene fluoride plastic into valuable chemicals. The dual‐single‐atom catalyst exhibits exceptional performance, with a total acetic/formic acid production of ∼1351.8 µmol g−1 ...

Exceptional Elasto‐Dielectric Properties in a Highly Flexible Dielectric Elastomer Composite: The Key Roles of Parallel Elastic Nanofibers

Advanced Materials Technologies, EarlyView.
Soft dielectric elastomer composites often face a trade‐off between enhanced dielectric properties and mechanical compliance. Here, a parallel‐aligned polyurethane nanofiber network embedded in PDMS creates a flexible, durable composite with increased permittivity, low modulus, and fatigue stability after 100,000 cycles.

Conductive Tin Oxide Under the Thermal Budget of Perovskite/TOPCon Tandems: Toward Indium‐Free Contacts

Advanced Materials Technologies, EarlyView.
This work demonstrates that achieving conductive undoped SnOx contacts required careful tailoring of oxygen vacancy (VO) tuning and defect engineering. Controlling oxygen deposition pressure and low‐temperature annealing (300°C) optimizes defect stoichiometry and mitigates carrier scattering. This low thermal budget approach significantly enhances Hall
