Faraday cage angled-etching of nanostructures in bulk dielectrics

, 2016
For many emerging optoelectronic materials, heteroepitaxial growth techniques do not offer the same high material quality afforded by bulk, single-crystal growth.

Facile Synthesis of CuxS Electrocatalysts for CO2 Conversion into Formate and Study of Relations Between Cu and S with the Selectivity

Advanced Functional Materials, EarlyView.
Copper sulfide based electrocatalysts for CO2 conversion are selective for production of formate as major product. Transformations under electrochemical conditions result in significant sulfur loss, and this study examines the nature of how persistent, residual sulfur (observed as surface SO42– species and S dissolved in the electrolyte) can sustain ...

Nanofabrication of Vertically Aligned 3D GaN Nanowire Arrays with Sub-50 nm Feature Sizes Using Nanosphere Lift-off Lithography

Proceedings, 2017
Vertically aligned 3D gallium nitride (GaN) nanowire arrays with sub-50 nm feature sizes were fabricated using a nanosphere lift-off lithography (NSLL) technique combined with hybrid top-down etching steps (i.e., inductively coupled plasma dry reactive ...

Evidence of Long‐Range Dzyaloshinskii–Moriya Interaction at Ferrimagnetic Insulator/Nonmagnetic Metal Interfaces

Advanced Functional Materials, EarlyView.
This study demonstrates that in sputter‐deposited Tb3Fe5O12 (TbIG)/nonmagnetic metal (NM) heterostructures, the interfacial Dzyaloshinskii–Moriya Interaction (DMI) originates at the TbIG/NM interface. Furthermore, measurements suggest a significant interfacial DMI arising from a second non‐local interface, created by inserting a Cu spacer layer between
