a and b The high-resolution transmission electron microscope image of the \(\hbox{WSe}_{2}\) single crystals in different axes and planes. The insets are the reciprocal lattice image of selected area electron diffraction patterns of the \(\hbox{WSe}_{2}\) single crystals in different axes and planes. c–k reveal lattice dislocation of the \(\hbox{WSe}_{2}\) single crystals at several locations in different axes and planes
