3D APT of high-purity Nb

The study of the surface chemistry of high-purity Nb is extremely important for the advancement of superconducting radio-frequency (SRF) cavities. The figure displays the 3-D reconstruction of Nb oxide on the surface of Nb. The reconstruction contains 300,000 atoms in 51 x 53 x 14 nm3 box. Nb atoms are in magenta, O atoms in cyan.
