Fig. 2: 1D local density profiles and 2D density contour plots at a void location.

From: Interpreting nanovoids in atom probe tomography data for accurate local compositional measurements

Fig. 2

a and c are results from NiCoCr; b and d are results from doped NiCoCrFe. To produce 1D profiles, 5 nm diameter cylindrical ROIs are oriented perpendicular to the hemispherical surface of the APT reconstruction and pass through the void. 27 × 27 × 3 nm cuboidal ROIs through the center of the voids are used to calculate the 2D density contour plot.
