Record Performance in Vertically Stacked, Solution‐Processed ZTO Schottky Diodes

open access: yesAdvanced Materials Technologies, EarlyView.
Schottky diodes based on solution processed sustainable zinc—tin–oxide thin films present an eco‐friendly and versatile alternative to conventional CMOS based technologies. Beyond state‐of‐the‐art performance for vertically stacked solution‐based oxide diodes was achieved, including rectification ratios exceeding nine orders of magnitude, and intrinsic

Coupling of Er3+ ions and Plasmonic Modes in Vertical Nanocavities for Spectral Broadening in Telecom Bands

open access: yesAdvanced Materials Technologies, EarlyView.
Left: Illustration of the glass & nanostructures system and the NIR emission at 1.5 µm, where the colored spheres represent the Er3+ ions within the doped glass. Right: Representation of the Stark splitting of the 4I13/2 and 4I15/2 manifolds of the Er3+, illustrating how the plasmonic modes facilitate the emission from the broader Stark manifold ...

Selective Reflection of Chiral Ferroelectric Nematic Liquid Crystals Tuned by Electric Field Along the Helix Axis

open access: yesAdvanced Optical Materials, EarlyView.
It is demonstrated that in chiral ferroelectric nematic liquid crystals sandwiched between electrically conducting transparent plates, the reflection color can be reversibly tuned by electric fields applied along the helix axis. The proposed theoretical model, assuming field‐induced coiling of the helix axis, accounts for all observations.
