Fabrication of recessed-gate AlGaN/GaN MOSFETs using TMAH wet etching with Cu ion implantation

Results in Physics
In this study, recessed-gate AlGaN/GaN MOSFETs were fabricated using a novel recess etching method––TMAH wet etching with Cu ion implantation. This innovative approach injects Cu ions selectively into the target AlGaN layer, creating defects that are ...

Investigation onto the Effect of Surface Etching using Chemical Etchants on the Dye-Ability of UHMWPE Fibre

Mehran University Research Journal of Engineering and Technology, 2021
Ultra high molecular weight fibre cannot be dyed using conventional dyeing techniques as they are extremely hydrophobic and do not possess any polar groups. Wet etching of the surface was used as the pre-treatment process to improve the dyeability of the

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.
