High-pressure growth of fluorine-free SmFeAsO superconducting single crystals
Hyun-Sook Lee, Jae-Hyun Park, Jae-Yeap Lee +6
Superconducting single crystals of SmFeAsO without fluorine doping were grown at a pressure of 3.3 GPa and a temperature of 1350-1450 C by using the self-flux metho…
Strong Influence of a Small Fiber on Shear Stress in Fiber-Reinforced Composites
MiKyoung Lim, KiHyun Yun
In stiff fiber-reinforced material, the high shear stress concentration occurs in the narrow region between fibers. With the addition of a small geometric change in cross-section,…
Effects of heat dissipation on unipolar resistance switching in Pt/NiO/Pt capacitors
S. H. Chang, S. C. Chae, S. B. Lee +8
We fabricated Pt/NiO/Pt capacitor structures with various bottom electrode thicknesses, , and investigated their resistance switching behaviors. The capacitors with $t_{BE}…
Abnormal Resistance Switching Behaviors of NiO Thin Films: Possible Occurrence of Simultaneous Formation and Rupture of Conducting Channels
Chunli Liu, S. C. Chae, S. H. Chang +8
We report the detailed current-voltage (I-V) characteristics of resistance switching in NiO thin films. In unipolar resistance switching, it is commonly believed that conducting fi…
