Large 1/f noise of unipolar resistance switching and its percolating nature
S. B. Lee, S. Park, J. S. Lee +8
We investigated the 1/f noise of Pt/NiO/Pt capacitors that show unipolar resistance switching. When they were switched from the low to high resistance states, the power spectral de…
Predictability of reset switching voltages in unipolar resistance switching
S. B. Lee, S. C. Chae, S. H. Chang +1
In unipolar resistance switching of NiO capacitors, Joule heating in the conducting channels should cause a strong nonlinearity in the low resistance state current-voltage (I-V) cu…
Percolation Model Explaining Both Unipolar Memory and Threshold Resistance Switchings in NiO Film
S. H. Chang, J. S. Lee, S. C. Chae +5
We observed two types of unipolar resistance switching (RS) in NiO film: memory RS at low temperature and threshold RS at high temperature. We explain these phenomena using a bond…
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…
Initial growth behavior and resulting microstructural properties of heteroepitaxial ZnO thin films on sapphire (0001) substrates
C. Liu, S. H. Chang, T. W. Noh +5
We have investigated the initial growth behavior and resulting microstructural properties of heteroepitaxial ZnO thin films prepared by pulsed laser deposition on sapphire (0001) s…
