Delocalized Charge Transport in Thermoelectric Composites of Semiconducting Carbon Nanotubes Wrapped with a P‐Type Polymer

Advanced Electronic Materials, EarlyView.
Composites made of semiconducting carbon nanotubes and p‐type polymers, when adequately doped with molecular dopants, can exhibit highly delocalized charge carrier transport, showing high thermoelectric performances. The efficient charge delocalization is enabled by the reduced coulombic binding energy at high carrier concentration and the small ...

Ag Nanowire‐Integrated MoS2/ZnO Heterojunctions for Highly Efficient Photogenerated Charge Transfer

Advanced Electronic Materials, Volume 11, Issue 6, May 2025.
A versatile strategy is reported for fabricating multi‐dimensional heterojunctions with significantly improved charge transfer capability. By integrating Ag nanowires with a MoS2/ZnO heterojunction, a fourfold increase in surface photovoltage is achieved, reaching 200 mV under visible light illumination.

Bandgap‐Dependent Doping of Semiconducting Carbon Nanotube Networks by Proton‐Coupled Electron Transfer for Stable Thermoelectrics

Advanced Electronic Materials, EarlyView.
Proton‐coupled electron transfer doping with benzoquinone is applied to p‐dope dense films of semiconducting single‐walled carbon nanotubes. The doping efficiency depends on the pH of the doping solution and the bandgap of the nanotubes. The highest conductivities and power factors are achieved for small‐bandgap nanotubes, remaining stable for over 120

Gate‐Dielectric Surface Engineering With Fluorinated Monolayers: Minimizing Contact Resistance and Nonidealities in OFETs

Advanced Electronic Materials, EarlyView.
Surface engineering of gate dielectrics with fluorinated self–assembled monolayers significantly improves the performance of organic field–effect transistors. In this study, Al2O3 functionalized with fluorinated phosphonic acids reduces contact resistance and hysteresis while achieving near‐zero threshold voltages, offering an alternative to ...

Decoding Interfacial Charge‐Carrier Dynamics in Integrated Perovskite/Organic Solar Cells via Numerical Modeling

Advanced Energy Materials, EarlyView.
A physical framework is developed based on drift‐diffusion simulations to elucidate the operation of integrated perovskite/organic solar cells (I‐POSCs) through the lens of interfacial charge‐carrier dynamics. A stepwise analysis establishes key links between carrier transport/recombination phenomena and device performance metrics, offering valuable ...

Photochemical N‐dealkylation of Tertiary Amines Coupled With Photocharging of Poly(Heptazine Imides)

Angewandte Chemie, EarlyView.
Protonated poly(heptazine imide) (H‐PHI) functions as an energy reservoir, thereby facilitating the endothermic dealkylation of triethylamine through a proton‐coupled two‐electron transfer (PC2ET) process. The extent of photocharging is quantitatively described by a molecular‐level descriptor, Ne:Nhept, providing a direct correlation between stored ...

Leveraging Digital Advanced Manufacturing to Enable Polymer Electrolyte Fuel Cells With Ultrahigh Gravimetric Power Density

Advanced Energy Materials, EarlyView.
This study employs digital advanced manufacturing to develop lightweight, compact porous distributors as alternatives to conventional bipolar plates in PEM fuel cells. A graphene‐coated nickel foam achieves a power density of 1.52 W cm−2, while titanium‐based designs deliver lightweight solutions: an LPBF‐fabricated Gyroid lattice reaches 1.36 W cm−2 ...
