PhD position in the field of vacuum electronics

The Nanophysics Center of Reykjavik University has an open PhD position in the field of vacuum electronics. The project includes computer simulations of the dynamics of the electron beam released by a microscopic cathode, and in particular by a Carbon nanotube fiber, either due to photoemission or due to field emission.

The effect of temperature, work function, cathode inhomogeneities, or ions present in the vacuum will be considered. The simulations will be compared with experimental results provided by a group of collaborators from outside Iceland or obtained at Reykjavik University, and the PhD student will have an opportunity to contribute to the experiments.

Interested candidates will contact:

  • Prof. Ágúst Valfells, e-mail:, or
  • Prof. Andrei Manolescu, e-mail, or
  • Dr. Kristnn Torfason, e-mail .
