Different Contrast Mechanisms in SEM Imaging of Graphene

WebMay 9, 2024 · Topographic contrast. In the SEM, topographic contrast arises from the dependence of the SE yield δ on the angle φ between the surface normal and the incident-electron beam. A simple geometrical argument, based on the fact that the irradiated volume of specimen lying within the escape depth is proportional to 1/cos(φ), gives δ(φ) = δ(0 ... WebTherefore, the contrasts of SEM images can be basically categorized by topographic, material, and voltage contrast. The topographic and material contrasts originate from yields ( SE yield and/or BSE yield), while the voltage contrast originates from variation of the collection efficiency of SEs. cinebench safe https://3dlights.net
