Tracing Sub‐Monolayer Contamination on Wafer‐Scale 2D Materials

Advanced Functional Materials, EarlyView.
Sub‐monolayer adventitious carbon contamination limits the performance and reproducibility of 2D material‐based devices. This study demonstrates scanning helium microscopy (SHeM) as a non‐destructive, ultra‐sensitive tool for wafer‐scale imaging of surface cleanliness.

Selenium‐Incorporated Polymerized Nonfullerene Acceptors/SWCNT Composites with Polymer‐Assisted n‐Doping for High‐Performance Organic Thermoelectrics

Advanced Functional Materials, EarlyView.
Selenium‐incorporated polymerized nonfullerene acceptor PCB2Se forms a strong supramolecular complex with SWCNTs, enabling a record‐high zT of 0.29. Sequential N‐DMBI doping, mediated through a polymer‐assisted electron‐transfer pathway, successfully converts the PCB2Se/SWCNT composite into an efficient n‐type material with an impressive power factor ...

Unlocking Multi‐Valley Energy Pockets and Interface‐Induced Phonon Filtering in InSb Thermoelectrics by Reaction‐Driven Interface Engineering

Advanced Functional Materials, EarlyView.
InSb, a narrow‐bandgap semiconductor with high carrier mobility, is promising for thermoelectric energy conversion but suffers from high lattice thermal conductivity and strong bipolar conduction. Here, in situ interface engineering using Co2O3 nanoprecursors forms hierarchical CoSbx/In2O3/CoSb3 heterostructures that enhance phonon scattering and ...

How the Carrier Mobility and Seebeck Coefficient of Doped Semiconducting Polymers Are Controlled by Counterion Interactions and Mesoscale Order

Advanced Functional Materials, EarlyView.
Conventional doping of P3HT with F4TCNQ results in poor charge transport. However, when F4TCNQ is exchanged with LiTFSI, the transport characteristics are greatly enhanced. We find the increase in charge transport is directly related to an increase in the mesoscale ordering of P3HT, resulting in longer and better‐connected transport pathways.

Efficient Membranes Made of a Nanohybrid of Fluorine‐Doped Carbon Dots Coupled With Metal Organic Framework for High‐Performance Vanadium Redox Flow Battery

Advanced Functional Materials, EarlyView.
A sulfonated poly(ether ether ketone)‐based hybrid membrane is fabricated with fluorine‐doped carbon dot (FCD) and functionalized metal organic framework (MIL−101−NH2). The novel design reduces unwanted ion crossover while maintaining a sufficient proton transport pathway.
