Field emission from crystalline niobium [PDF]

Physical Review Special Topics - Accelerators and Beams, 2009
Appreciable suppression of field emission (FE) from metallic surfaces has been achieved by the use of improved surface cleaning techniques. In order to understand the effects of surface preparation on field emission, systematic measurements were performed on five single crystal and three large grain samples of high purity (RRR>300) niobium by means of ...

Capacitive effect in ultrafast laser-induced emission from low conductance diamond nanotips

New Journal of Physics, 2020
Single crystal diamond nanotips reveal a new behavior for ultrafast laser-induced electron emission. Under tightly focused femtosecond laser illumination, electron yield shows a saturation with the laser intensity. When the DC bias is sufficient for dark
