Mechanical Stress Evolution in Polycrystalline Ge Thin Films Under MeV Ion Irradiation

Advanced Materials Interfaces, EarlyView.
Irradiation of polycrystalline Ge thin films with 1.8 MeV Au ions alters residual stress through defect generation and lattice expansion. Increasing fluence drives progressive lattice disorder and eventual amorphization. Polycrystalline Ge resists amorphization longer than crystalline Ge, as grain boundaries facilitate defect diffusion, significantly ...

A Readout Circuit Applied for an Ultrafast CMOS Image Sensor

Photonics
Microchannel plate gated framing camera is commonly used in inertial confinement fusion diagnostics. However, it is a vacuum electronic device with bulkiness and non-single-line-of-sight imaging. To reduce the size of the camera and achieve a single line

Topological Point Defects in SmC* Liquid Crystals Under Mechanical Disturbance

Advanced Materials Interfaces, EarlyView.
Tangetial air jet shear inducess island formation and nucleates topological point defects in uniform SmC films. Island bounded by edge dislocation loops shrink and transform into isolated point defects under continued shear. Mechanical perturbatio provides a controllable route for defect engineering in smectric liquid crystal thin films.

Passivated SiC Surfaces for Photonic and Quantum Applications: Balancing Chemical Stability and Surface Luminescence

Advanced Materials Interfaces, EarlyView.
Low‐temperature passivation of SiC reveals that optical surface quality and chemical stability are not directly correlated. Ar plasma‐treated and SiNx‐passivated surfaces yield the lowest photoluminescence background, whereas CF4 plasma and ALD‐grown dielectrics introduce higher emission.

Hierarchical Structure and Fabrication of Functionally Graded Biointerfaces in the Mussel Byssus

Advanced Materials Interfaces, EarlyView.
The byssus is a fibrous protein‐based holdfast consisting of mechanically distinct interfaces, which mussels use to anchor their soft living tissue to hard seashore surfaces. Here, multiscale methodologies were used to elucidate the compositional and structural features underlying these functionally graded interfaces and how they are fabricated through

Record High Polarization at 2 V and Imprint‐Free Operation in Superlattice HfO2‐ZrO2 by Proper Tuning of Ferro and Antiferroelectricity

Advanced Materials Technologies, EarlyView.
Low‐power ferroelectric capacitors, based on superlattice HfO2‐ZrO2 is reported. With proper tuning of ferro and antiferroelectricity, an imprint‐free high switchable polarization charge (2Pr of 76 µC/cm2) is obtained with 2MV/cm leading to linear analog weight update and non‐volatile retention, providing a design guideline for emerging non‐volatile ...
