Physical Self-Assembly And Nano-Patterning

Nano Wires by Self Assembly

We present a technique to fabricate nano wires on silicon substrates without any lithography. The wires are 50 nm or less in width, but their lengths can be 10s of micro meters. They can be formed by a single or multiple layers of metals. The wires can be designed to form a network which can be partially released from the substrate to form 3D structures. Such structures may serve as actuators o...

Self-patterning Gd nano-fibers in Mg-Gd alloys

Manipulating the shape and distribution of strengthening units, e.g. particles, fibers, and precipitates, in a bulk metal, has been a widely applied strategy of tailoring their mechanical properties. Here, we report self-assembled patterns of Gd nano-fibers in Mg-Gd alloys for the purpose of improving their strength and deformability. 1-nm Gd nano-fibers, with a 〈c〉-rod shape, are formed and he...

DNA BASED SELF-ASSEMBLY AND NANO-DEVICE: THEORY AND PRACTICE by Peng Yin Department of Computer Science Duke University

Self-assembly, modularity, and physical complexity.

We present a quantitative measure of physical complexity, based on the amount of information required to build a given physical structure through self-assembly. Our procedure can be adapted to any given geometry, and thus, to any given type of physical structure that can be divided into building blocks. We illustrate our approach using self-assembling polyominoes, and demonstrate the breadth of...
