Figure 3: (a) TEM image of clustered CuO NPs. (b) HRTEM image of CuO NP showing high degree of crystallinity with random orientations. (c) HRTEM examination of single CuO NP. (d) Zoom-in view of crystal showing well aligned atomic planes with 2.9 Å spacing. (e) FFT of the image shown in (c) matching the [101] zone axis for the monoclinic structure.
