Nanoprocessing of layered crystalline materials by atomic force microscopy.

Miyake S, Wang M - Nanoscale Res Lett (2015)

Bottom Line: By taking advantage of the mechanical anisotropy of crystalline materials, processing at a single-layer level can be realized for layered crystalline materials with periodically weak bonds.Moreover, it is easy to image the atoms on the basal plane, where the processed shape can be observed on the atomic level.It also summarizes recent AFM results obtained by our research group regarding the atomic-scale mechanical processing of layered materials including mica, graphite, MoS2, and highly oriented pyrolytic graphite.

ABSTRACT
By taking advantage of the mechanical anisotropy of crystalline materials, processing at a single-layer level can be realized for layered crystalline materials with periodically weak bonds. Mica (muscovite), graphite, molybdenum disulfide (MoS2), and boron nitride have layered structures, and there is little interaction between the cleavage planes existing in the basal planes of these materials. Moreover, it is easy to image the atoms on the basal plane, where the processed shape can be observed on the atomic level. This study reviews research evaluating the nanometer-scale wear and friction as well as the nanometer-scale mechanical processing of muscovite using atomic force microscopy (AFM). It also summarizes recent AFM results obtained by our research group regarding the atomic-scale mechanical processing of layered materials including mica, graphite, MoS2, and highly oriented pyrolytic graphite.

Fig5: Original images (a) and filtered images (b) of AFM and FFM images of muscovite.

Mentions: Surface images of the cleavage basal plane of muscovite observed by SPM are shown in Figure 5; (a) shows the original AFM and FFM images, and (b) shows their 2D-filtered counterparts. The surface of the cleavage plane was flat except for occasional bumps; its roughness was within 0.2 nm. The friction force and atomic force distributions had the same periodicity as the hexagons formed by SiO4 tetrahedra. The measured periodicity between areas of high friction force was nearly 0.5 nm, which was in agreement with the expected interval periodicity of 0.52 nm.Figure 5
