Enhancing Charge Transport and Extraction in Ta3N5 Photoanodes Via Ti Doping and TiN Contact Layers

Small, EarlyView.
Ta3N5${\rm Ta}_3{\rm N}_{5}$ is a promising photoanode for solar water splitting but suffers from poor charge transport and interfacial losses. We combine Ti compensation doping with ultrathin TiN back‐contact interlayers to suppress bulk recombination, enhance carrier mobility and lifetime, and enable efficient carrier extraction, yielding ...

Spectroscopic Signatures of Doping in Thin Films of Semiconducting Single‐Walled Carbon Nanotubes

Small, EarlyView.
This review presents an overview of the spectroscopic changes of semiconducting single‐walled carbon nanotubes upon chemical, electrochemical or electrostatic doping. The presence of holes or electrons directly affects visible to far‐infrared absorption, near‐infrared fluorescence and electroluminescence as well as Raman spectra, which enables in‐situ ...

Do We Really Know Why Carbon Nanotubes Grow?

Small, EarlyView.
The CNT growth mechanism is still debated. We propose a heterogeneous (2D) classical nucleation framework comparing pathways for graphenic patches, caps, and full CNTs. Despite its simplicity, it rationalizes key trends, including the correlation between catalyst particle size and CNT diameter.

Combinatorial Synthesis of BaCu2Se2 Thin Films: Effect of Composition on Crystal Structure and Optoelectronic Properties

Small, EarlyView.
The emerging BaCu2Se2 semiconductor compound is synthesized in combinatorial thin film libraries for fast screening of its fundamental properties related to the application in sustainable energy sources. Ba‐rich and Cu‐rich compositions are explored.
