Challenges in materials and devices for Resistive-Switching-based Neuromorphic Computing
Javier del Valle, Juan Gabriel Ramírez, Marcelo J. Rozenberg +1
This tutorial describes challenges and possible avenues for the implementation of the components of a solid-state system, which emulates a biological brain. The tutorial is devoted…
Growth-Induced In-Plane Uniaxial Anisotropy in VO/Ni Films
Dustin A. Gilbert, Juan Gabriel Ramírez, Thomas Saerbeck +4
We report on a strain-induced and temperature dependent uniaxial anisotropy in VO/Ni hybrid thin films, manifested through the interfacial strain and sample microstruct…
Non-equilibrium phase precursors to the insulator-metal transition in V2O3
Andrej Singer, Juan Gabriel Ramirez, Ilya Valmianski +11
The discovery of novel phases of matter is at the core of modern physics. In quantum materials, subtle variations in atomic-scale interactions can induce dramatic changes in macros…
Ultrafast Electron-Lattice Coupling Dynamics in VO2 and V2O3 Thin Films
Elsa Abreu, Stephanie N. Gilbert Corder, Sun Jin Yun +11
Ultrafast optical pump - optical probe and optical pump - terahertz probe spectroscopy were performed on vanadium dioxide (VO2) and vanadium sesquioxide (V2O3) thin films over a wi…
Search for New Superconductors: An Electro-Magnetic Phase Transition in an Iron Meteorite Inclusion at 117 K
Stefan Guénon, Juan Gabriel Ramírez, Ali C. Basaran +3
The discovery of superconductivity in pnictides and iron chalcogenides inspires the search for new iron based superconducting phases. Iron-rich meteorites present a unique opportun…
Dynamic conductivity scaling in photoexcited V2O3 thin films
Elsa Abreu, Siming Wang, Gabriel Ramirez +4
Optical-pump terahertz-probe spectroscopy is used to investigate ultrafast far-infrared conductivity dynamics during the insulator-to-metal transition (IMT) in vanadium sesquioxide…
