Comparison of calculated, simulated and measured signal amplification in a variable pressure SEM

Abstract: This paper presents computed dependencies of signal amplification of detected electrons on the water vapor pressure in a variable pressure SEM using the EOD software equipped with a Monte Carlo plug-in. We analyze the amplification at selected energies of signal electrons going through a high-pressure water vapor and total signal amplification by including a realistic simulation of the secondary emission from sample. The results are compared with experimental measurements and the dependencies of published analytical models. [Copyright &y& Elsevier]
