Nano-lithography on pristine oxide surface
Nano-lithography done by adatom manipulation with scanning tunneling microscope tip on fractured Nb-doped SrTiO3 surface. The line width is ~20 nm.
Field of Flowers
Reflected light microscopy image of self-assembled supercrystals from 4.7 nm PbS nanoparticles. The color variation originates from light interference.
