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…
