D profilometry based on modulation measurement (MMP) depends on the modulation distribution of the sinusoidal fringes projected on objects. The projecting direction is the same as the detecting direction, it can measure the objects with shadow, discontinuous height steps and spatial isolation on them. The detailed introduction on the principle and processing method of MMP and the measuring results for an object are presented. The results proved that MMP was correct in principle and effective in actual...

In the course of a systematic search for stable silicon surfaces, we have studied four stable high index silicon surfaces, i.e., Si(1,1,11), (1 0 8), (2 1 2), and (15,1,17), by analyzing their low energy electron diffraction (LEED) patterns. The results show not only that all these surfaces are stable but also that Si(15,1,17) is a major stable surface,whereas the rest three are minor stable surfaces, meaning that their unit cells consist of a nanometer facet of a major stable surface along with a double height...

In the course of a systematic search for stable silicon surfaces, we have studied four stable high index silicon surfaces, i.e., Si(1,1,11), (1 0 8), (2 1 2), and (15,1,17), by analyzing their low energy electron diffraction (LEED) patterns. The results show not only that all these surfaces are stable but also that Si(15,1,17) is a major stable surface,whereas the rest three are minor stable surfaces, meaning that their unit cells consist of a nanometer facet of a major stable surface along with a double height step. In view of the periodic facet step morphology of these minor stable surfaces, we suggest that these surfaces have the potential to be used as templates for growth of periodic nanowires of some suitable materials.
