This paper presents a MEMS device for simultaneous mechanical and electrical characterization of individual nanowires. The device consists of an electrostatic actuator and two capacitive sensors, enabling it to acquire all mechanical measurement data (force and displacement) electronically without relying on electron microscopy imaging. Electrical insulation within the suspended structures of the...
This paper presents a microelectromechanical systems (MEMS) device for simultaneous electrical and mechanical characterization of individual nanowires. The device consists of an electrostatic actuator and two capacitive sensors, capable of acquiring all measurement data (force and displacement) electronically without relying on electron microscopy imaging. This capability avoids the effect of electron...
Inter-nanotube mass transport along the central pores of carbon nanotubes (CNTs) is a fundamental problem for CNT-based nanofluidic devices. Besides the interest for testing classical theories of fluid flow at the nanoscale, CNT fluidic junctions are basic elements for more complex fluidic systems. Controlled melting, evaporation and flowing of copper and tin intra-/inter-nanotube shells are investigated...
Relative displacements between the atomically smooth, nested shells in multiwalled carbon nanotubes (MWNTs) can be used as a robust nanoscale motion enabling mechanism for transduction applications such as bearings, switches, GHz-oscillators, shuttles, memories, syringes and actuators. Here we report on a batch fabrication paradigm suited for structuring large arrays of MWNTs into such devices in...
Functionalized quantum dots have been successfully attached to multi-walled carbon nanotubes over carbodiimide-assisted coupling. Characterization in a transmission electron microscope shows the quantum dots are attached mainly at the opened tips and defect sites on the side-walls of nanotubes, suggesting the covalent nature of the bonding and high selectivity to chemically reactive sites. Due to...
Based on self-scrolling of Si/Cr bilayer films on Si(001) wafers, various micro- and nanostructures including micro-claws, microtubes, helical nanobelts, nanorings and nanospirals are fabricated in a controllable way. The scrolling principles of the structures from Si/Cr bilayer films are discussed. The flexibility of individual Si/Cr nanospirals and nanorings has been investigated using a nanorobotic...
The contact phase of an assembly task involving micro and nano-sized building blocks is complicated by the presence of surface and intermolecular forces such as electrostatic, surface-tension and Van der Waals forces. Assembly strategies must account for the presence of these forces in order to guarantee successful repeatable micro and nanoassembly with high precision. In this paper, a detailed model...
