Phase noise analysis and control of VO-based relaxation type oscillators
Artem Litvinenko, Erbin Qiu, Sambit Ghosh +5
The paper investigates phase noise in VO₂‑based relaxation oscillators, identifying thermal fluctuations during the incubation phase as the main cause of linewidth broadening, and…
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…
Disorder-driven stochastic dynamics in Mott resistive-switching systems
David J. Alspaugh, Lorenzo Fratino, Nareg Ghazikhanian +2
Controlled disorder in correlated materials provides a new route to emergent stochastic dynamics in neuromorphic hardware. Here we show that focused ion beam irradiation in VO$_{2}…
Jamming-controlled stochasticity in metal-insulator switching
Nicolò D'Anna, Nareg Ghazikhanian, Katherine Matthews +5
Understanding and controlling phase transitions is a fundamental part of physics and has been central to many technological revolutions, from steam engines to field-effect transist…
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…
