This new program is capable of simulating more than 100,000 primary incident electrons in a few minutes. The required input parameters for the Monte Carlo simulations are obtained from first-principles calculations. The calculated dielectric constants, total electron density of states, and work function were used to obtain the inelastic mean free path and stopping power of systems. As a case study, the Cu surface was chosen since it has been thoroughly explored and simulations can be compared with available experimental measurements of secondary electron emission. The goal of this thesis is to investigate the secondary electron emission of both clean Cu (110) surfaces and carbon-coated Cu systems. It was shown that the adsorption of the carbon layer on the Cu (110) surface can reduce the secondary electron emission.37en-USMonte CarloSecondary electron emissionCarbon coveragesCu (110)Thesis
