Tuesday publication post! 📖 In this newest publication, from the #BrnoUniversityofTechnology, authors Peter Kepic and others have looked into phase transformation of single VO₂ NPs using the #FusionAX system.
Vanadium dioxide (VO₂) is a cornerstone material for nanophotonic metamaterials and next-gen memory devices, thanks to its reversible insulator–metal transition (IMT). While this transition has been studied extensively in thin films, the nanoscale dynamics of individual single-crystal VO₂ nanoparticles (NPs)—the fundamental building blocks of these systems—remain largely unexplored.
What can we learn from this paper?
🔥The particles displayed a statistical distribution of transition temperature and steepness across heating and cooling cycles.
🔎 It was seen that there was a stability of coexisting phases, crucial for memory applications.
🔬Lastly, persistent multilevel memory behavior at near-room temperature was observed, using just a few VO₂ NPs.
By resolving these nanoscale hysteresis dynamics, tunable optoelectronic and memory devices can be synthesized with enhanced functionalities.
