Scientific Achievement
3D nanoprinting (focused electron beam deposition) followed by purification leads to purely metallic plasmonic structures with predetermined nanoscale geometries.
Significance and Impact
This achievement places 3D nanoprinting by focused electron beam induced deposition at the forefront of 3D direct-write.
Research Details
– 3D nanostructures are deposited using focused electron beam induced deposition.
– Subsequently, a beam induced H2O reaction occurs inside the deposit, converting the initial gold-carbon composite into pure gold.
– Electron energy loss spectroscopy revealed never before seen spatial variations in energy dependent plasmon resonances.
