Nanoporous Microtubes via Oxidation and Reduction of Cu–Ni Commercial Wires
Metals, 2017 Metallic porous microtubes were obtained from commercial wires (200–250 µm diameter) of Cu-65Ni-2Fe, Cu-44Ni-1Mn and Cu-23Ni, alloys (wt. %) by surface oxidation at 1173 K in air, removal of the unoxidized core by chemical etching, and reduction in ...

Anisotropic Etching of Graphite and Graphene in a Remote Hydrogen Plasma [PDF]
, 2017 We investigate the etching of a pure hydrogen plasma on graphite samples and graphene flakes on SiO$_2$ and hexagonal Boron-Nitride (hBN) substrates. The pressure and distance dependence of the graphite exposure experiments reveals the existence of two ...

Synthesis and electrochemical properties of V2C MXene by etching in opened/closed environments
Journal of Advanced Ceramics, 2020 The effect of etching environment (opened or closed) on the synthesis and electrochemical properties of V2C MXene was studied. V2C MXene samples were synthesized by selectively etching of V2AlC at 90 °C in two different environments: opened environment ...

Mechanisms of Thermal Atomic Layer Etching.
Accounts of Chemical Research, 2020 ConspectusAtomic layer control of semiconductor processing is needed as critical dimensions are progressively reduced below the 10 nm scale. Atomic layer deposition (ALD) methods are meeting this challenge and produce conformal thin film growth on high ...

Influence of the epitaxial composition on N-face GaN KOH etch kinetics determined by ICP-OES
Beilstein Journal of Nanotechnology, 2020 Roughening by anisotropic etching of N-face gallium nitride is the key aspect in today’s production of blue and white light emitting diodes (LEDs). Both surface area and number of surface angles are increased, facilitating light outcoupling from the LED ...
