Abstract :
We propose a new method describing a charge-up phenomenon induced by electron beam in Teflon film from a microscopic viewpoint. The physical model of the 1 eV-30 keV electron scattering in the insulating polymer is used to calculate the charge distribution inside Teflon film. The electric field and the potential distribution as a function of the irradiation time are calculated from Poisson´s equation. The relaxation of the charge density under its own electric field is not considered in the present method. The calculated surface potential is in good agreement with our experimental data.
