Abstract:

Field evaporation of silicon as positive and negative ions in the field ion microscope and scanning tunneling microscope configurations is investigated with the charge-exchange model using atomic potentials from an empirical potential due to Tersoff [Phys. Rev. B 37, 6991 (1988)] and an environment dependent potential developed by Bolding and Andersen [Phys. Rev. B 41, 10568 (1990)]. For the geometry of the field ion microscope, Si+ should be the observable ion species. In the close-spaced electrode geometry of the scanning tunneling microscope, Si2- should be the favored ion species since it requires the lowest evaporation field.
