    Abstract

    LiCoPO4 nanocrystals are synthesized via a supercritical fluid process at 380 °C for 1 h and we visualize Li/Co antisite defects along two crystallographic directions using annular dark and bright field scanning transmission electron microscopy (STEM). The antisite defects are observed with bright/dark contrast produced by Co atoms in Li columns in both HAADF (high angle annular dark field) and ABF (annular bright field) images viewed along [010] directions. Interestingly, few antisite defects are observed along [101] directions with weak contrast and P atoms are observed near to Co atoms. This journal is
