Edge effect on the current-temperature characteristic of thermionic cathodes
Anna Sitek, Kristinn Torfason, Andrei Manolescu +1
We perform a computational study, based on the molecular dynamics method, of the shape of Miram curves obtained from microscale planar diodes. We discuss the smooth transition from…
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…
Space-Charge Limited Current from a Finite Emitter in Nano- and Microdiodes
Johannes Bergur Gunnarsson, Kristinn Torfason, Andrei Manolescu +1
We simulate numerically the classical charge dynamics in a microscopic, planar, vacuum diode with a finite emitter area and a finite number of electrons in the gap. We assume elect…
Space-charge effects in the field-assisted thermionic emission from nonuniform cathodes
Anna Sitek, Kristinn Torfason, Andrei Manolescu +1
We use computational simulations to study the electron emission and propagation in planar vacuum diodes. We show how space-charge affects thermionic emission from cathodes with two…
