Improved Hopfield Network Optimization using Manufacturable Three-terminal Electronic Synapses
Su-in Yi, Suhas Kumar, R. Stanley Williams
We describe via simulation novel optimization algorithms for a Hopfield neural network constructed using manufacturable three-terminal Silicon-Oxide-Nitride-Oxide-Silicon (SONOS) s…
Size scaling, dynamics, and electro-thermal bifurcation of VO2 Mott oscillators
Stephanie M. Bohaichuk, Suhas Kumar, Miguel Muñoz Rojo +7
Traditional electronic devices are well-known to improve in speed and energy-efficiency as their dimensions are reduced to the nanoscale. However, this scaling behavior remains unc…
In-operando synchronous time-multiplexed O K-edge x-ray absorption spectromicroscopy of functioning tantalum oxide memristors
Suhas Kumar, Catherine E. Graves, John Paul Strachan +4
Memristors are receiving keen interest because of their potential varied applications and promising large-scale information storage capabilities. Tantalum oxide is a memristive mat…
Molecular dynamics simulations of oxide memristors: crystal field effects
S. E. Savel'ev, A. S. Alexandrov, A. M. Bratkovsky +1
We present molecular-dynamic simulations of memory resistors (memristors) including the crystal field effects on mobile ionic species such as oxygen vacancies appearing during oper…
Modulation of Negative Index Metamaterials in the Near-IR Range
Evgenia Kim, Wei Wu, Ekaterina Ponizovskaya +5
Optical modulation of the effective refractive properties of a "fishnet" metamaterial with a Ag/Si/Ag heterostructure is demonstrated in the near-IR range and the associated fast d…
Alloying mechanisms for epitaxial nanocrystals
M. S. Leite, G. Medeiros-Ribeiro, T. I. Kamins +1
The different mechanisms involved in the alloying of epitaxial nanocrystals are reported in this letter. Intermixing during growth, surface diffusion and intra-island diffusion wer…
