Three-dimensional reconstruction of one part of p-type SiNW characterized by laser-assisted APT. The reconstruction volume is 16 × 16 × 58 nm3. The red and black dots represent Si and B atoms, respectively. From the reconstruction, it can be seen that, B atoms are homogeneously distributed in the SiNW core with a relatively high concentration: 1.4 ± 0.1 × 1020 B/cm3.
