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…
How Well Can Graphs Represent Wireless Interference?
Magnus M. Halldorsson, Tigran Tonoyan
Efficient use of a wireless network requires that transmissions be grouped into feasible sets, where feasibility means that each transmission can be successfully decoded in spite o…
Cavity-photon-switched coherent transient transport in a double quantum waveguide
Nzar Rauf Abdullah, Chi-Shung Tang, Andrei Manolescu +1
We study a cavity-photon-switched coherent electron transport in a symmetric double quantum waveguide. The waveguide system is weakly connected to two electron reservoirs, but stro…
Signature of snaking states in the conductance of core-shell nanowires
Tomas Orn Rosdahl, Andrei Manolescu, Vidar Gudmundsson
We model a core-shell nanowire (CSN) by a cylindrical surface of finite length. A uniform magnetic field perpendicular to the axis of the cylinder forms electron states along the l…
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…
Computational Optimization, Modelling and Simulation: Recent Trends and Challenges
Xin-She Yang, Slawomir Koziel, Leifur Leifsson
Modelling, simulation and optimization form an integrated part of modern design practice in engineering and industry. Tremendous progress has been observed for all three components…
