Ligand‐Mediated Shape Engineering of SWIR InAs Colloidal Quantum Dots for Photodetector Applications
Advanced Materials, EarlyView.The table of contents: A robust ligand‐engineering strategy is introduced for SWIR InAs CQDs synthesized from amino‐arsine precursors. Bulky OA ligands induce controlled shape evolution, allowing access to >1700 nm absorption under mild conditions. Halide‐based inkification enables photodetectors with 19.1% EQE at 1300 nm and detectivity exceeding 1010

Advanced Materials, EarlyView.Asymmetric lamellar templating at the perovskite/C60 interface is achieved using a laterally polarized indole spacer. Surface anchoring and Ind–Ind assembly form a π‐rich lamellar interphase that supports uniform C60 contact formation, suppresses recombination, preserves electron extraction, and enables certified high‐efficiency cells and modules with ...

Fabrication of TiN/TiO2 Nanotube‐Based Heterostructure for Hydrogen Sensing Applications
Advanced Materials Interfaces, EarlyView.A hydrogen sensor based on titanium dioxide nanotubes coated with titanium nitride has been developed. The coating process causes a mixed titanium oxynitride layer to form, which improves the sensor performance. Sensor response R depends on the TiN thickness and is not degraded after 7 days in air.

Transparent thin film transistors of polycrystalline SnO2−x and epitaxial SnO2−x
AIP Advances, 2020 We report on transparent thin film field effect transistors (TFTs) based on polycrystalline SnO2−x and epitaxial SnO2−x. Polycrystalline SnO2−x TFTs of the top and the bottom gate geometries exhibited high mobility values of 145.7 cm2/V s and 160.0 cm2/V

Low‐Temperature Gold Deposition Improves CdTe Back Contacts
Advanced Materials Interfaces, EarlyView.Cd(Se,Te) samples are cooled during the evaporation of Au back contacts to thermally quench CdTe degradation. Reduced temperature during Au evaporation boosts PV efficiency, open‐circuit voltage, and fill factor. XPS associates these improvements with less chemical perturbation of the CdTe surface during metallization.
