APS March Meeting 2024

We presented the voltage-driven insulator-to-metal transition (IMT) in NbO₂, highlighting its potential for neuromorphic computing. Through transport and noise spectroscopy, we uncover the dynamic coexistence of conducting phases and demonstrate tunable relaxation oscillators based on nanoscale NbO₂ films.

APS March Meeting 2023

We explored the effects of Pb and Cu bi-intercalation in vanadium oxide bronzes, revealing tunable charge ordering and resistive switching behavior. Our findings highlight the role of intercalated ions in enhancing correlated electron behavior, offering insights into the design of materials with tailored electronic properties.

APS March Meeting 2023

We presented the switching behavior of vanadium oxide bronzes, revealing their potential as synaptic devices for neuromorphic computing.
