A voltage-responsive strongly dipolar-coupled macrospin network with emergent dynamics for computing
Xinglong Ye, Zhibo Zhao, Qian Wang +15
Emergent behavior, which arises from local interactions between simple elements, is pervasive in nature. It underlies the energy-efficient computing in our brains. However, realizi…
Plasma engineered Hydroxyl Defects in NiO a DFTSupported-Spectroscopic Analysis of Oxygen Hole States and Implications for Water Oxidation
Harol Moreno Fernandez, Mohammad Amirabbasi, Crizaldo Jr. Mempin +8
Controlling lattice oxygen reactivity in earth abundant OER catalysts requires precise tuning of defect chemistry in the oxide lattice. Here, we combine DFT+U calculations with pla…
