1. Influence of non-dipole transitions on the extraction of EMCD
University essay from Uppsala universitet/MaterialteoriAbstract : ELNES-spectra of the L3 and L2-edge of bcc-iron are simulated using a Bloch wave method for the calculation of the DDSCS within a 1st-order Born approximation of the inelastic electron scattering process in order to study the influence of non-dipole terms on the EMCD-signal. The necessary electronic structure information is obtained from a DFT-calculation using WIEN2k. READ MORE

2. Shape functions in calculations of differential scattering cross-sections
University essay from Institutionen för fysik och astronomiAbstract : Two new methods for calculating the double differential scattering cross-section (DDSCS) in electron energy loss spectroscopy (EELS) have been developed, allowing for simulations of sample geometries which have been unavailable to earlier methods of calculation. The new methods concerns the calculations of the thickness function of the DDSCS. READ MORE
