Room Temperature Ferroelectric Ferromagnet in 1D Tetrahedral Chain Network
Kyeong Tae Kang, Chang Jae Roh, Jinyoung Lim +17
Ferroelectricity occurs in crystals with broken spatial inversion symmetry. In conventional perovskite oxides, concerted ionic displacements within a three-dimensional network of t…
Ferroelectric switching dynamics of topological vortex domains in a hexagonal manganite
Myung-Geun Han, Yimei Zhu, Lijun Wu +6
Field-induced switching of ferroelectric domains with a topological vortex configuration is studied by atomic imaging and electrical biasing in an electron microscope, revealing th…
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…
Scaling behaviors of RESET voltages and currents in unipolar resistance switching
S. B. Lee, S. C. Chae, S. H. Chang +4
Unipolar switching phenomena have attracted a great deal of recent attention, but the wide distributions of switching voltages still pose major obstacles for scientific advancement…
Strong resistance nonlinearity and third harmonic generation in the unipolar resistance switching of NiO thin films
S. B. Lee, S. C. Chae, S. H. Chang +6
We investigated third harmonic generation in NiO thin films, which exhibit unipolar resistance switching behavior. We found that the low resistance states of the films were strongl…
