Building and Manipulating Three-Dimensional and Linked Two-Dimensional Structures of Nanoparticles Using Scanning Force Microscopy
نویسندگان
چکیده
Manipulation of nanoparticles with the scanning force microscope (SFM) has been limited until now to clearing areas on a surface or to moving single particles sequentially to create two-dimensional patterns. The research reported here uses a previously described setup for nanomanipulation with the SFM to (i) build a simple three-dimensional pyramidal structure by pushing a nanoparticle on top of two others and (ii) rotate and translate a linked two-particle structure. The experiments are conducted in air and at room temperature with gold nanoparticles deposited on silicon previously coated with a silane layer.

متن کاملA versatile atomic force microscope for three-dimensional nanomanipulation and nanoassembly.
A conventional atomic force microscope (AFM) has been successfully applied to manipulating nanoparticles (zero-dimensional), nanowires (one-dimensional) or nanotubes (one- or two-dimensional) by widely used pushing or pulling operations on a single surface. However, pick-and-place nanomanipulation in air is still a challenge. In this research, a modified AFM, called a three-dimensional (3D) man...

Due to electrical properties (high electron mobility) and electrochemical characteristics (high electron transport rate), graphene-based materials have been widely applied for various scientific fields. However, due to their two-dimensional structures, these materials have low active sites for reaction. Therefore, changing from two-dimensional sheets dimensional to the three-dimensi...
