Large optical field enhancement for nanotips with large opening angles
Sebastian Thomas, Georg Wachter, Christoph Lemell +2
We theoretically investigate the dependence of the enhancement of optical near-fields at nanometric tips on the shape, size, and material of the tip. We confirm a strong dependence…

Probing of optical near-fields by electron rescattering on the 1 nm scale
Sebastian Thomas, Michael Krüger, Michael Förster +2
We present a new method of measuring optical near-fields within ~1 nm of a metal surface, based on rescattering of photoemitted electrons. With this method, we precisely measure th…
