[Audio] NCN NEMS: Tutorials

This presentation will describe thermal transport processes at solid-solid material interfaces. An overview of applications in the electronics industry will serve to motivate the subject, and then the basic diffusive constriction theory will be developed. The addition of carbon nanotube arrays to solid-solid interfaces has been shown to improve heat transfer significantly, and these materials will serve as an example of enhanced transport with nanomaterials. Experimental techniques and results will be reviewed, and a model that employs ballistic transport principles will be introduced to interpret these results.

This talk will discuss some of the new opportunities That arises by precisely controlling fluid flow and mixing using microfluidicdevices. I describe studies to elucidate mechanisms of drop formation and use these to create new fluid structures that are difficult to achieve with my other method. I also show how the exquisite control afforded by the Microfluidic devices provides the enabling technology to use droplets as nanoreactors to qualitatively increase the rate of combinatorial screening ofChemical reactions.

This seminar is an introduction to the MEMS technology as itapplies to RF and Microwave systems. Besides discussing several key RFMEMS components (switches, varactors, inductors), reconfigurable circuitarchitectures will also be introduced. In addition, reliability and costconsiderations as applied to the future of the RF MEMS technology willbe included.

Micro- and nanoscaled fluid mechanics are rapidly emerging as important supporting fields in biomedical technology, nanotechnology, etc., as well as being important fields of study in their own right. Despite the common use of these terms in the literature, the fluid behavior at these small length scales is quite often misunderstood. The topics of continuum breakdown, electrokinetics, and surface phenomena will be discussed in this presentation and hopefully some light shed on what nanofluidics really is.

This talk will introduce hierarchical physical models and efficient computational techniques for coupled analysis of electrical, mechanical and van der Waals energy domains encountered in Nanoelectromechanical Systems (NEMS). Numerical results will be presented for several silicon nanoelectromechanical switches to demonstrate the static electromechanical pull-in behavior.

Atomic Force Microscopy (AFM) is an indispensible tool in nano science for the fabrication, metrology, manipulation, and property characterization of nanostructures. This tutorial reviews some of the physics of the interaction forces between the nanoscale tip and sample, the dynamics of the oscillating tip, and the basic theory of some of the common modes of AFM operation. The tutorial summarizes some of the exciting new applications of Atomic Force Microscopy.
