[求助] 晶体生长方向,晶面间距如何让计算

高手请教纳米晶表征问题
Figure 3 shows a typical transmission electron microscope
(TEM) image and high-resolution TEM (HRTEM) image of the
obtained sample, along with selected area electron diffraction
(SAED) pattern. HRTEM images in images c and d in Figure
3 show lattice spacings of ca. 2.23, and 5.95 Å, respectively,
corresponding to the lattice spacings of the (110) planes, and
(001) planes for trigonal tellurium, respectively. The corresponding
SAED pattern taken along the [110] direction on the
Te tubes indicated that it is single crystalline (Figure 3b). The
combination of the results by HRTEM and the SAED pattern
confirmed that the axis of the nanotube is along the [001]
direction,
