Target diameter (nm) for reliable single NP dewetting
Case Study: Nanocylinder Dewetting at 700°C
At an annealing temperature of 700°C, VO2 nanocylinders exhibit a crucial transformation. Nanocylinders with diameters up to 350 nm reliably dewet into single nanoparticles. Beyond this, larger nanocylinders tend to break into multiple particles, with an average final diameter stabilizing around 220 nm. This provides a deterministic window for fabricating single, tailored nanoparticles, crucial for precise device integration. The process demonstrates a robust path to achieving desired nanoscale architectures for advanced computing.
