Optimization Study of Charcoal Observation with Scanning Electron Microscope in Various Operating Conditions

Abstract

Scanning electron microscopy (SEM) has been widely used in the development of science, especially in the field of materials science. The development of SEM as a tool of material analysis has also experienced very rapid development. However, in practice, the use of SEM for analysis requires setting parameters that cannot be generalized between materials. This study conducted to analysis charcoal morphology on various parameters of SEM operation. From the result of the study, it is known that some SEM operation parameters such as voltage accelerate, spot intensity, working distance and objective aperture influence the results of charcoal morphology analysis with SEM.
