Optical micrograph of as-grown single crystal rhombus platelet (left), and other microstructures such as pyramids and wires as observed using SEM arising out of a platelet surface (inset) with the wires growing from the apex and side of the pyramids (bar in the inset is ). On the right a leaflike platelet is shown (bars are ).
EDS spectrum obtained on the plates.
Dark field TEM image of a platelet surface and edge (left) and representative SAED pattern obtained on the same platelet (middle). On the right: the identified main crystallographic orientations for the rhombic platelet is also shown with a separate coordinate system introduced to facilitate the visualization of the growth of the structures with , , and directions corresponding to , , and  directions, respectively.
TEM image of an elbowlike structure typically found at one of the ends (left); SAED pattern shows polycrystalline structure of tip (circular area B). SAED patterns obtained on multiple locations, including areas shown as A and C, confirm their structural similarity with the platelet.
