(Invited) towards a vertical and damage free post-etch InGaAs fin profile: dry etch processing, sidewall damage assessment and mitigation options [PDF]
, 2015 Based on current projections, III-Vs are expected to replace Si as the n-channel solution in FinFETs at the 7nm technology node. The realisation of III-V FinFETs entails top-down fabrication via dry etch techniques. Vertical fins in conjunction with high

The Effect of Purcell Cavities on the Lifetime of Thermally Activated Delayed Fluorescent Emitters
Advanced Functional Materials, EarlyView.A pressing challenge to OLED displays and lighting is to balance high efficiency and long operational lifetime in the deep blue spectrum. The Purcell effect can reduce the triplet density and hence the probability for destructive energy‐driven triplet annihilation events that limit the OLED lifetime. Here we study of the Purcell effect on two different

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 ...

3D Patterning of Si by Contact Etching With Nanoporous Metals
Frontiers in Chemistry, 2019 Nanoporous gold and platinum electrodes are used to pattern n-type silicon by contact etching at the macroscopic scale. This type of electrode has the advantage of forming nanocontacts between silicon, the metal and the electrolyte as in classical metal ...

Advanced Functional Materials, EarlyView.High‐energy electron impact in plasma catalysis often causes excessive dissociation of active intermediates, limiting C2+ product selectivity. To address this challenge, a bio‐inspired stoma‐shell nanoarchitecture is designed to decouple electron impact from catalytic reaction zones.
