Figure 3

High resolution transmission electron microscopy results (HRTEM) of the MnGe nanodots. (a) A high-magnification TEM image showing several aligned MnGe nanodots. (b) The HRTEM images of the MnGe nanodots (the selected area in (a)) showing a perfect diamond structure as the Ge matrix. (c, d) Bragg filterings of ± (111) (c) and ± ( 1 1 ¯ 1 ¯ ) (d) reflections, respectively; where no dislocation or distortion was observed. The dark contrast of the nanodots indicates the existence of significant strain.
