Abstract:Growth steps and 2D nuclei are observed by AFM on the {0 0 1} faces of MnHg(SCN)4(C2H6OS)2 (MMTD) crystals. Measurements of the heights of steps and nuclei show the lowest value is equal to c/4. According to the interplanar distance modification established by Donney and Harker, the lowest height should be c/2. Appearance of the sub-layer growth is correlative with the crystal structure of MMTD.
Keywords:Steps  Atomic force microscopy  2D nucleation  Crystal structure  Nonlinear optical materials
