Circular Polarimetric Imaging with a Metamaterial Integrated Long‐Wavelength Infrared Focal Plane Array

Advanced Science, EarlyView.
A quantum well infrared photodetector based long‐wavelength infrared division‐of‐focal‐plane‐array circular polarimeter featuring a 320 × 256 pixel array integrated with a chiral meta‐mirror structure array is established. The device achieves a circular polarization extinction ratio of 5.67, a 9.13‐fold enhancement in responsivity, a noise equivalent ...

Me‐4PACz Functionalized MXene for Halide Perovskite Solar Cells

Advanced Science, EarlyView.
Functionalized Ti₃C₂ MXene nanoneedles with Me‐4PACz employed at the interface between perovskite and Spiro‐OMeTAD, improve charge extraction, energy alignment, and surface hydrophobicity. Devices show boosted PCE (21.5%) and operational stability (T88 = 1000 h, ISOS‐L‐1), highlighting MXene:Me‐4PACz as a powerful strategy for simultaneously improving ...

High Electron Charge Carrier Mobility in the Nematic Phase of a Roof‐Shaped Nematogen with Optimum Molecular Biaxiality

Advanced Science, EarlyView.
Liquid Roofs. Biaxial roof‐shaped mesogens self‐assemble in a nematic phase of a broad temperature range exhibiting high TOF electron mobilities. These mesogens possess the almost optimum biaxial aspect ratio. The results from X‐ray, polarized optical microscopy, modeling, and TOF data agree with biaxiality of small domains and transient nematic phase ...
