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.

(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
