Unveiling the Nottingham Inversion Instability during the thermo-field emission from refractory metal micro-protrusions

Autor: Darius Mofakhami, Benjamin Seznec, Tiberiu Minea, Romaric Landfried, Philippe Testé, Philippe Dessante

Publikováno v: Scientific Reports, Vol 11, Iss 1, Pp 1-12 (2021)

Abstract The electron emission by micro-protrusions has been studied for over a century, but the complete explanation of the unstable behaviors and their origin remains an open issue. These systems often evolve towards vacuum breakdown, which makes e

Magnetic properties of optimized cobalt nanospheres grown by focused electron beam induced deposition (FEBID) on cantilever tips

Autor: Soraya Sangiao, César Magén, Darius Mofakhami, Grégoire de Loubens, José María De Teresa

Publikováno v: Beilstein Journal of Nanotechnology, Vol 8, Iss 1, Pp 2106-2115 (2017)

In this work, we present a detailed investigation of the magnetic properties of cobalt nanospheres grown on cantilever tips by focused electron beam induced deposition (FEBID). The cantilevers are extremely soft and the cobalt nanospheres are optimiz

Publikováno v: Journal of Applied Physics. 132:243302

In the last decades, numerical simulation has become a precious tool to assist the design and study of electron sources based on regular arrays of field emitters. Simulations of field emitter arrays (FEAs) require 3D treatment to account for the inte

Thermal effects in field electron emission from idealized arrangements of independent and interacting micro-protrusions

Autor: Philippe Dessante, Romaric Landfried, Tiberiu Minea, Darius Mofakhami, Benjamin Seznec, Philippe Testé

Publikováno v: Journal of Physics D: Applied Physics
Journal of Physics D: Applied Physics, IOP Publishing, 2021, 54 (23), pp.235305. ⟨10.1088/1361-6463/abd9e9⟩

Modelling studies of thermo-field electron emission (TFE) from protrusions at a cathode surface usually use simulations in 2D axial symmetry. Indeed, time-dependent simulations in 3D are very demanding in computation time. Often, 3D simulations have
