Signal amplification in simple metal-insulator transition devices
Victor Palin, Nareg Ghazikhanian, Matthew Frame +3
Signal dissipation in large-scale neural networks can lead to information loss and ultimately to computational failures, necessitating local signal amplification at neuron - synaps…
Inhibitory neuristor based on metal-to-insulator transition
Victor Palin, Akash Agnihotri, Nareg Ghazikhanian +4
Mimicking the collective excitatory and inhibitory behaviors of biological neurons remains a critical challenge in the development of neuromorphic computing systems that rival the…
Electrically induced ferromagnetism in an irradiated complex oxide
Nareg Ghazikhanian, Pavel Salev, Dayne Sasaki +2
In metal-insulator transition materials, a small perturbation can shift the delicate balance between competing or coexisting electronic phases, leading to dramatic changes of the m…
Accurate prediction of macroscopic transport from microscopic imaging via critical fractals at the Mott transition
P. -Y. Chen, A. R. Rajapurohita, M. Alzate Banguero +7
Vanadium dioxide (VO) exhibits hysteresis in resistance while undergoing a thermally driven insulator-metal transition (IMT). Understanding the nonequilibrium effects in resist…
Effects of Interactions and Defect Motion on Ramp Reversal Memory in Locally Phase Separated Materials
Y. Sun, M. Alzate Banguero, P. Salev +4
The ramp-reversal memory (RRM) effect in metal-insulator transition metal oxides (TMOs), a non-volatile resistance change induced by repeated temperature cycling, has attracted con…
Enhanced stochasticity in irradiated vanadium oxide oscillators
Nareg Ghazikhanian, David J. Alspaugh, Pavel Salev +3
Insulator-to-metal transition materials are highly sensitive to even minute deviations of stoichiometry, lattice defects, and disorder, which provides opportunities to engineer the…
