FORMATION OF ANTIREFLECTIVE SILICON SURFACES BY ELECTROCHEMICAL AND CHEMICAL METHODS

Information and Telecommunication Sciences, 2017
Background. Application of the silicon-based porous textures as an efficient and commercially viable coating has to be maximally adapted to processes of the silicon solar cell manufacturing. To improve the antireflective property of Si frontal surface it

Progress in metal-assisted chemical etching of silicon nanostructures

Procedia CIRP, 2020
Abstract Metal-assisted chemical etching (MACE) is a simple, low-cost method for fabricating silicon nanostructures. In this paper, the recent progress of MACE to control silicon nanostructures is reviewed. The principle of MACE is briefly summarized.

Gold- and Silver-Nanoparticle-Assisted Etching of p-Si and n-Si: A Discussion of Etching Behavior Based on Polarization Curves

Electrochemistry
Metal-assisted etching (metal-assisted chemical etching) is increasingly recognized as a crucial method for fabricating silicon (Si) nanostructures. This process involves the dissolution of Si both directly beneath metal catalysts (local etching) and at ...

Low‐Angle Grain Boundaries and Re‐Segregation in Single‐Crystalline Ni‐Base Superalloys

Advanced Engineering Materials, EarlyView.
This work demonstrates that Re‐segregation at low‐angle grain boundaries (LAGBs) in Ni‐base superalloys is influenced by misorientation angle. Advanced microscopy and atom probe tomography reveal that higher misorientation angles increases Re‐segregation.

Towards Defect Phase Diagrams: From Research Data Management to Automated Workflows

Advanced Engineering Materials, EarlyView.
A research data management infrastructure is presented for the systematic integration of heterogeneous experimental and simulation data required for defect phase diagrams. The approach combines openBIS with a companion application for large‐object storage, automated metadata extraction, provenance tracking and federated data access, thereby supporting ...

Recycling of NiTi Shape Memory Alloys: Fundamental and Technological Aspects of a Vacuum Induction Melting Processing Route

Advanced Engineering Materials, EarlyView.
The present study investigates recycling of NiTi shape memory alloys via vacuum induction melting. An ingot was synthesized from elemental Ni and Ti and subjected to three subsequent remelting cycles. Remelting increases process durations and impurity levels and adversely affects microstructures and functional properties.

Influence of Scan Strategies in Electron Beam Powder Bed Fusion on Solidification, Microstructure, and High‐Temperature Compressive Properties of γ′‐Strengthened Inconel 738LC

Advanced Engineering Materials, EarlyView.
Experiments and thermophysical simulations were conducted to investigate the electron beam powder bed fusion electron beam (PBF‐EB/M) process for the γ′‐strengthened nickel‐based superalloy Inconel 738LC. The results demonstrate the impact of process‐induced microstructural variations on high‐temperature mechanical behavior, providing a basis for ...
