Simulating electron energy loss spectroscopy with the MNPBEM toolbox

چکیده

Within the MNPBEM toolbox, we show how to simulate electron energy loss spectroscopy (EELS) of plasmonic nanoparticles using a boundary element method approach. The methodology underlying our approach closely follows the concepts developed by Garćıa de Abajo and coworkers [for a review see Rev. Mod. Phys. 82, 209 (2010)]. We introduce two classes eelsret and eelsstat that allow in combination with our recently developed MNPBEM toolbox for a simple, robust, and efficient computation of EEL spectra and maps. The classes are accompanied by a number of demo programs for EELS simulation of metallic nanospheres, nanodisks, and nanotriangles, and for electron trajectories passing by or penetrating through the metallic nanoparticles. We also discuss how to compute electric fields induced by the electron beam and cathodoluminescence.

Plasmonics simulations with the MNPBEM toolbox: Consideration of substrates and layer structures

Within the MNPBEM toolbox, developed for the simulation of plasmonic nanoparticles using a boundary element method approach, we show how to include substrate and layer structure effects. We develop the methodology for solving Maxwell’s equations using scalar and vector potentials within the inhomogeneous dielectric environment of a layer structure. We show that the implementation of our approac...

Non-Isothermal Degradation Kinetics of High Energy Protons Irradiated Polyvinyl Butyral

This research is aimed to undertake a comparative study on stability and thermal degradation kinetics of un-irradiated and high energy protons irradiated polyvinyl butyral (PVB) based on weight loss analysis and non-isothermal approaches. The weight loss by the un-irradiated PVB upon heating was found to be in two stages but due to high energy protons accelerated exposure following by chemical ...
