Design, development and validation of electron ionisation models for nano-scale simulation

By ?????????


Two theory-driven models of electron ionization cross sections, the Binary-Encounter-Bethe model and the Deutsch-M??rk model, have been design and implemented; they are intended to extend the simulation capabilities of the Geant4 toolkit. The resulting values, along with the cross sections included in the EEDL data library, have been compared to an extensive set of experimental data, covering more than 50 elements over the whole periodic table.The authors express their gratitude to CERN for support to the research described in this paper. The authors thank Sergio Bertolucci, Elisabetta Gargioni, Simone Giani, Berndt Grosswendt, Vladimir Grichine, Andreas Pfeiffer and Lina Quintieri for valuable discussions. CERN Library???s support has been essential to this study; the authors are especially grateful to Tullio Basaglia. This work was supported by the Nuclear Research and Development Program in Korea through the Radiation Technology Development Program and the Basic Atomic Energy Research Institute (BAERI). Support also was received from the Korean Ministry of Knowledge Economy (2008-P-EP-HM-E-06-0000)/the Sunkwang Atomic Energy Safety Co., Ltd
