Journal ArticleDOI
Activity–Stability Trends for the Oxygen Evolution Reaction on Monometallic Oxides in Acidic Environments
Nemanja Danilovic,Ramachandran Subbaraman,Kee-Chul Chang,Seo Hyoung Chang,Yijin Kang,Joshua Snyder,Arvydas P. Paulikas,Dusan Strmcnik,Yong-Tae Kim,Deborah J. Myers,Vojislav R. Stamenkovic,Nenad M. Markovic +11 more
TL;DR: It is found that the most active oxides are, in fact, the least stable materials, and the best materials for the OER should balance stability and activity in such a way that the dissolution rate is neither too fast nor too slow.
Journal ArticleDOI
Using Surface Segregation To Design Stable Ru‐Ir Oxides for the Oxygen Evolution Reaction in Acidic Environments
Nemanja Danilovic,Ramachandran Subbaraman,Kee-Chul Chang,Seo Hyoung Chang,Yijin Kang,Joshua Snyder,Arvydas P. Paulikas,Dusan Strmcnik,Yong-Tae Kim,Deborah J. Myers,Vojislav R. Stamenkovic,Nenad M. Markovic +11 more
TL;DR: A new synthesis strategy is developed that is based on tuning the near-surface composition of Ru and Ir elements by surface segregation, thereby resulting in the formation of a nanosegregated domain that balances the stability and activity of surface atoms.
Journal ArticleDOI
Random Circuit Breaker Network Model for Unipolar Resistance Switching
Seung Chul Chae,Jae Sung Lee,Sejin Kim,Shinbuhm Lee,Seo Hyoung Chang,Chunli Liu,Byungnam Kahng,Hyunjung Shin,Dong-Wook Kim,Chang Uk Jung,Sunae Seo,Sunae Seo,Myoung-Jae Lee,Myoung-Jae Lee,Tae Won Noh +14 more
TL;DR: Noh et al. as discussed by the authors proposed a percolation model based on a network of circuit breakers with two switchable metastable states to explain the reversible resistance switching behavior in polycrystalline TiO2 thin capacitors.

Journal ArticleDOI
Occurrence of Both Unipolar Memory and Threshold Resistance Switching in a NiO Film
Seo Hyoung Chang,Jae Sung Lee,Suyong Chae,Shinbuhm Lee,Chunli Liu,Byungnam Kahng,Dong-Wook Kim,Tae Won Noh +7 more
TL;DR: It is shown that the RS effects are governed by the thermal stability of the filaments, which arise from competition between Joule heating and thermal dissipation.
