(a) Image of a broken NCD microtip, cut by FIB; and NCD regions are marked by blue- and red-dotted arrows, respectively. (b) Typical cross-sectional bright-field TEM image of a NCD microtip specimen.

Image of FIG. 3.
FIG. 3.

(a) HRTEM images taken at the interface between and NCD [indicated by red -dotted square in Fig. 2(b)]. Lower inset: diffuse rings collected from a thin layer of near the surface. (b) Highly magnified view of a set of (111) diamond lattice planes. Inset: corresponding ED pattern. (c) EDS performed in the amorphous region of (a).
