We here report a simple and efficient method to grow single-layer bismuth nanoparticles (BiNPs) with various sizes on glass substrates. Optimal conditions were found to be 200°C and 0.12 W/cm 2 at a growth rate of 6 Å/s, with the deposition time around 40 s. Scanning electron microscope (SEM) images...
