Spectroscopic Ellipsometry of Conducting Anisotropic Pedot thin Films

Macromolecular Rapid Communications, EarlyView.
We measure the optical response of poly[3,4‐ethylenedioxythiophene] thin films through the combination of polarized photon spectroscopies (variable‐angle ellipsometry, UV–mid‐IR reflectance and transmittance) and wide‐angle X‐ray scattering, revealing anisotropic optical response and conductivity and enabling structural modelling of chain and π‐system ...

Interlinkages Between Financial Markets and Minerals (1990–2023): Implications for Global Energy Transitions and Environmental Sustainability

Sustainable Development, EarlyView.
ABSTRACT This paper examines the nexus between financial markets (FM), mineral resources, and global energy transitions (ET) between 1990 and 2023 in the 20 leading countries exporting mineral resources, focusing on their impact on environmental sustainability.

Strategy for One‐Step Optimization of Metal Oxide Passivating Contact Materials for Si Heterojunction Solar Cells through Growth Angle Variation

Small, EarlyView.
A one‐step oblique angle reactive sputtering approach enables simultaneous tuning of bulk and interfacial stoichiometry in a metal oxide/ silicon heterojunction. In case of vanadium oxides, growth angle variation controls the formation of stoichiometric SiO2, ternary SiOx(V) interlayer, and phase purity of vanadium oxide, considerably simplifying the ...

Tuning Optoelectronic Properties and Photoelectrochemical Performance of β‐TaON via Vanadium Doping

Small, EarlyView.
Vanadium‐doped β‐TaON is studied to elucidate how controlled cation substitution modulates crystal and electronic structures and photoelectrochemical performance. Moderate vanadium incorporation (<10 at.%) retains phase purity, narrows the bandgap, and improves charge transport, whereas excessive doping (>10 at.%) induces secondary phases that suppress

Vacancy‐Induced Z‐Contrast Anomaly in Self‐Assembled (Ti,V)O2 Heterostructure

Small, EarlyView.
This study investigates the unexpectedly high contrast observed in ADF‐STEM imaging of spinodal decomposed (Ti,V)O2 heterostructure. In situ heating, GPA, and EELS analyses reveal that oxygen vacancies accumulate in V‐rich layers due to facilitated vacancy migration along [001]R pathways during phase separation by spontaneous ionic diffusion.
