High‐Performance and Ultrafast Single Germanium Nanowire Photodetectors

open access: yesAdvanced Optical Materials, EarlyView.
Semiconductor nanowire‐based photodetectors with high sensitivity and fast photoresponse in the near‐infrared wavelength range are crucial for applications in light‐wave communication switches, as well as environmental and atmospheric sensing. Here, the fabrication of an axial p‐n junction along single germanium nanowires and their photoresponse ...

Enhancement of the Optoelectric and Photovoltaic Responses of Al/PVP:ZnTiO3/p‐Si Structure by Graphene Nanoparticles

open access: yesAdvanced Photonics Research, EarlyView.
This study investigates the optoelectronic response of Al/p‐Si photodiodes with and without a (PVP:Gr‐ZnTiO3) interlayer under varying light intensities. Key parameters are analyzed, revealing that the interlayer enhances photosensitivity, optical responsivity, and specific detectivity.

Picomolar Detection of Tau Protein Using 1D Photonic Crystal Biochips for Alzheimer's Disease Diagnosis

open access: yesAdvanced Sensor Research, EarlyView.
Elevated levels of Tau in cerebrospinal fluids or other body fluids are associated with the progression of Alzheimer's disease. An optical technique, based on a dual label‐free and fluorescence operation mode, is developed to detect Tau protein in both standard running buffer and cerebrospinal fluid.

When Two Becomes Three: Predicting Stable Ternary Boron‐Based Compounds by Populating Unique Lattice Sites in Binary Prototype Structures

open access: yesAdvanced Theory and Simulations, EarlyView.
By substituting lattice sites in 16 binary prototypes, over 27 000 boron‐based ternary compounds are studied, revealing 155 stable candidates. The analysis identifies 31 compounds with superior hardness and elastic moduli compared to their binary counterparts.
