FRACTAL BEHAVIOR OF ELECTRON-SCATTERING IN SOLIDS

The fractal behaviour of electron scattering in solids is studied with electron trajectories simulated by Monte Carlo simulations. More precisely, the box-counting dimension of electron trajectories in C, Cu, Ag, and Au is determined. Then, the fractal dimension curve of the position of an electron in function of time simulated in a gold target shows that the first part of the electron trajectory is described by a persistent process and that the last part is described by random walk process. Finally, the multifractal behaviour of an electron trajectory simulated in gold is presented.
