Monolithic Integration of Silicon Nanowires With a Microgripper

Low Voltage Thermo-mechanically Driven Monolithic Microgripper with Piezoresistive Feedback

Pick-and-place of micro/nano sized objects means handling of very tiny and very different in properties objects having specific behavior. Besides formal requirements of assembly processes, the tools for controllable manipulation with these objects should not affect the examined micro/nano environment, i.e. should be “small and passive” in any sense. Despite of the recent progress, most availabl...

New concept for the monolithic integration of optoelectronic circuits on Silicon substrate: Silicon Photonics

Monolithic integration of erbium-doped amplifiers with silicon-on-insulator waveguides.

Monolithic integration of Al2O3:Er3+ amplifier technology with passive silicon-on-insulator waveguides is demonstrated. A signal enhancement of >7 dB at 1533 nm wavelength is obtained. The straightforward wafer-scale fabrication process, which includes reactive co-sputtering and subsequent reactive ion etching, allows for parallel integration of multiple amplifier and laser sections with silico...

Thermal conductance calculations of silicon nanowires: comparison with diamond nanowires

: We present phonon thermal conductance calculations for silicon nanowires (SiNWs) with diameters ranging from 1 to 5 nm with and without vacancy defects by the non-equilibrium Green's function technique using the interatomic Tersoff-Brenner potentials. For the comparison, we also present phonon thermal conductance calculations for diamond nanowires. For two types of vacancy defects in the SiNW...

A Monolithic Shape Memory Alloy Microgripper for 3-D Assembly of Tissue Engineering Scaffolds

This paper describes a microgripper used for the micro-assembly of an artificial scaffold for tissue engineering. The porous sponge-like scaffold is a three dimensional construct built by tiny unit parts of biodegradable polymer. This application requires the assembly of several parts by applying a suitable level of force. In this framework, a monolithic shape memory alloy (SMA) microgripper wa...
