Dynamics of a Field Emitted Beam from a Microscopic Inhomogeneous Cathode
Kristinn Torfason, Anna Sitek, Andrei Manolescu +1
We investigate by molecular dynamics simulations [arXiv:1412.4537 [physics.plasm-ph], arXiv:1608.06789 [physics.plasm-ph]] a beam of electrons released via field emission from a pl…
Molecular Dynamics Simulations of Field Emission From a Prolate Spheroidal Tip
Kristinn Torfason, Agust Valfells, Andrei Manolescu
High resolution molecular dynamics simulations with full Coulomb interactions of electrons are used to investigate field emission from a prolate spheroidal tip. The space charge li…
Molecular Dynamics Simulations of Field Emission From a Planar Nanodiode
Kristinn Torfason, Agust Valfells, Andrei Manolescu
High resolution molecular dynamics simulations with full Coulomb interactions of electrons are used to investigate field emission in planar nanodiodes. The effects of space charge…
Synchronization in arrays of vacuum microdiodes
Marjan Ilkov, Kristinn Torfason, Andrei Manolescu +1
Simulations have shown that space-charge effects can lead to regular modulation of photoemitted beams in vacuum diodes with gap sizes on the order of 1 micron and accelerating volt…
