Femtosecond laser-induced electron emission from nanodiamond-coated tungsten needle tips
Alexander Tafel, Stefan Meier, Juergen Ristein +1
We present femtosecond laser-induced electron emission from nanodiamond-coated tungsten tips. Based on the shortness of the femtosecond laser pulses, electrons can be photo-excited…

Fabrication and structural characterization of diamond-coated tungsten tips
Alexander Tafel, Mingjian Wu, Erdmann Spiecker +2
Coating metal nanotips with a negative electron affinity material like hydrogen-terminated diamond bears promise for a high brightness photocathode. We report a recipe on the fabri…

Ultrafast scanning electron microscope applied for studying the interaction between free electrons and optical near-fields of periodic nanostructures
M. Kozák, J. McNeur, N. Schönenberger +6
In this paper we describe an ultrafast scanning electron microscope setup developed for the research of inelastic scattering of electrons at optical near-fields of periodic dielect…
