A High‐Resolution THz‐PCF Sensing Framework: Precise Identification of Food Preservatives Through Refractive Index Analysis

open access: yesAdvanced Materials Interfaces, EarlyView.
As presented in the graphical abstract, it depicts an image of a terahertz photonic crystal fiber (THz‐PCF) sensor with a polygonal shape in the core, which is filled with an analyte, and air slots in the cladding. The THz waves will travel through the fiber, and due to increased light‐matter interaction in the sensing region, changes in refractive ...

Grafted Low‐Leakage Si/AlN p‐n Diodes Enabled by Fluorinated AlN Interface

open access: yesAdvanced Materials Interfaces, EarlyView.
This work demonstrates a fluorination‐based interface engineering strategy that transforms oxygen‐terminated AlN surfaces into fluorine‐terminated interfaces for grafted p‐Si/n‐AlN diodes. By combining pseudo‐ALE oxide removal, XeF2 fluorination, and ultrathin SiNx stabilization, the engineered interface suppresses defect‐assisted reverse leakage by ...
