Waveguide Photoactuators: Materials, Fabrication, and Applications

Advanced Robotics Research, EarlyView.
Waveguide photoactuators convert guided light into mechanical motion. Their tethered‐flexible design enables minimally invasive surgery and confined‐space robotics. This review aims to guide materials selection, device design, and system integration, accelerating the transition of waveguide photoactuators from laboratory prototypes to versatile ...

Combined etching technology for controlling surface damage precursors to improve laser damage resistance of fused silica

Results in Physics
At present, a single post-processing technology will always introduce secondary defects (trace pollution elements and structural defects) while removing surface processing defects of fused silica components, which limits the further improvement of the ...

Proximal probe-like nano structuring in metal-assisted etching of silicon

AIP Advances, 2019
We use silicon having multiple crystalline orientation domains and high metal doping in metal assisted chemical etching (MACEtch) in HF/H2O2. In device-quality silicon, MACEtch produces high-aspect ratio anisotropic (1-D) structures (wires, columns ...

Etching-Controlled Growth of Graphene by Chemical Vapor Deposition

, 2017
Graphene growth and etching are reciprocal processes that can reach a dynamic balance during chemical vapor deposition (CVD). Most commonly, the growth of graphene is the dominate process, while the etching of graphene is a recessive process often ...
