TEM study of silicon carbide whisker microstructures

The second type of whisker contained stacking faults spaced relatively widely also on {111} planes but now on the planes inclined to the [111] axis of the whisker. This leads to a characteristic chevron contrast in the TEM. This second type of whisker had a much smoother surface profile than the first type with perpendicular defects.
