Figure 2A shows the TEM image of the AACH microfibers. The SAED pattern (the inset of Figure 2A) recorded from the face of the crystal having the longest axis (for example, the circled area in the TEM image) alaways exhibits the same single-crystalline pattern, consistent with the [001] zone of AACH crystals. The elongated microfiber shape with the exposed (001) faces demonstrated that the AACH crystal preferably grew along the crystallographic c axis under the synthesis conditions Figure 2. (A) TEM image and a typical SAED pattern (inset) of a single-crystal AACH fiber. The SAED pattern is conformed to be the [001] zone of the AACH crystal (reflections: A, (020); B, (200)) and indicates the direction of AACH microfiber growth if perpendicular to the [100] crystallographic axis. |
