Curtain effect free(CEF) is a new CP method for heterogeneous materials.
CP is a commonly-used tool for cross-section sample preparation with ion beams. How to avoid structure deformation during preparation, especially for heterogenous materials, is a task. MSS delivers a new CP method, CEF, to decrease such effect as low as possible.
▪ Wider observation area than CP
▪ Reducing curtain effect
▪ Pristine surfaces can be preserved
