Posted by admin / Under Bessel Potential
Optically trapped microspheres write nanofeatures on bumpy surfaces nanotechweb.org The technique uses a Bessel beam optical trap to position a sub-micron polystyrene sphere in water on a polyimide substrate in the xy plane. In the z direction, the Bessel beam scattering force and the surface repulsion force compensate each other to ... |
