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…

Correlative mapping of local hysteresis properties in VO
Melissa Alzate Banguero, Sayan Basak, Nicolas Raymond +6
We have developed a new optical microscopy technique able to track micron-sized surface clusters as temperature is varied. Potential candidates for study include phase separated me…
