Wood‐Derived Nanocellulose‐Biocarbon Fresnel‐Zone Plate Lenses for Sub‐THz Frequency Applications

Advanced Materials Technologies, EarlyView.
Wood‐derived nanocellulose and lignin‐based biocarbon were combined to fabricate fully bio‐based Fresnel zone plate (FZP) lenses for sub‐terahertz frequencies. These sustainable FZP lenses exhibit low dielectric loss and high directivity, achieving performance comparable to that of metallic references, and remain functional under environmental stress ...

Laser‐Induced Local De‐Doping in Organic Semiconductors

Advanced Materials Technologies, EarlyView.
The polymer PBTTT‐C14 doped with the small molecule acceptor F4TCNQ is considered as a benchmark material system. Mask‐free, microscale patterning of the doping level via laser‐induced heating and sublimation of dopant molecules is shown. Controlling laser irradiance and swath spacing allows dopant level control with laser‐limited resolution, opening ...

Wafer‐Scale Top‐Down Patterning of Metal Halide Perovskites

Advanced Materials Technologies, EarlyView.
Wafer‐scale patterning of metal halide perovskite films is demonstrated on 150 mm substrates using a chemically amplified resist, polymethyl methacrylate (CAR‐PMMA) and a single reactive ion etching step. The streamlined process preserves film luminescence while defining submicrometer features across the full wafer, enabling dense, scalable integration
