Electron Energy Loss Spectroscopy Theory Including the Effectof Electromagnetic Retardation

We have developed a theory of electron energy loss spectra (EELS) for reflection geometry that includes the electromagnetic retardation effect. This theory analytically reduces to the standard EELS result when $\frac{\omega}{c}$ is much smaller than |k//|, where ω and k// are the frequency and the w...

Description
Summary:We have developed a theory of electron energy loss spectra (EELS) for reflection geometry that includes the electromagnetic retardation effect. This theory analytically reduces to the standard EELS result when $\frac{\omega}{c}$ is much smaller than |k//|, where ω and k// are the frequency and the wavevector parallel to the sample surface, respectively, of an elementary excitation created in the scattering process. As a concrete example we calculate the energy loss probability for a Au sample including the electromagnetic retardation effect.
