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…

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…
