“…(3) that involves the unknown electrostatic influence factor K. This factor may be determined either by using the decay charge stage when the discharge exists [11] or by measuring the change of secondary electron image size of the sample under electron irradiation associated to the simulation of electron beam deflection [see Appendix A]. Since the magnitude of the discharge is very low, after the interruption of electron beam, K is calculated using the second method.…”

“…However space charge accumulation and discharge together with related trapping-detrapping phenomena are still relevant. Our current work is aimed at making use of the displacement-current method [11], which is based on the electrostatic influence phenomenon. The corresponding arrangement attached to a scanning electron microscope is able to measure simultaneously the displacement current arising from the variation of the trapped charge (during and after electron irradiation) and the leakage currents.…”

Phys. 95, 731 (2004); 10.1063/1.1632015 Quantitative measurement of surface potential and amount of charging on insulator surface under electron beam irradiationThe charge properties, under electron irradiation, of three types of glasses are studied by employing scanning electron microscope ͑SEM͒ associated with the technique called the electrostatic influence method. The experimental conditions are closed to those of typical field emission display ͑FED͒ operation. To determine the amount of trapped charges during and after electron irradiation, a special arrangement adapted to the SEM was used. This arrangement allows displacement and leakage currents to be simultaneously measured. The secondary electron emission yield during electron irradiation is also deduced. The trapping ability of each glass is analyzed taking into account the regulation mechanisms involved under electron irradiation. Finally useful indications permitting an adequate selection of glasses that may be used as FED spacers are deduced.
