Title:
Nanotribology and nanomechanics and applications to MEMS/NEMS and Bio-MEMS/Bio-NEMS
Time:7 hours
Description and objectives
Nanotechnology undoubtedly is expected to be of major industrial significance.
The nanotechnology is still in its infancy and the emphasis to date has been on
the fabrication and laboratory demonstration of individual components. The field
of MEMS/NEMS has expanded considerably over the last decade. Micro/Nanosystems
have begun to be commercially used. MEMS/NEMS devices are produced by various
lithographic and nonlithographic fabrication processes. Silicon-based MEMS/NEMS
devices are made from single-crystal silicon, LPCVD polysilicon films and other
ceramic films. For high temperature applications, SiC and other films are being
developed to replace polysilicon films. There are bioadhesion issues in BioMEMS/BioNEMS
which need to be addressed. Tribology of various devices which require relative
motion is of importance.
The scale of operation and large surface-to-volume ratio of the devices
result in very high retarding forces such as friction and adhesion that
seriously undermine the performance and reliability of the devices. These are
tribological phenomena that need to be studied and understood at the micro- to
nanoscales. In addition, materials for these devices must exhibit good micro/nanoscale
tribological and mechanical properties. There is a need to develop lubricants
and identify lubrication methods that are suitable for these devices.
Measurement and evaluation of mechanical properties of micro/nanoscale
structures is essential to help address reliability issues. Using atomic force
microscopy-based techniques, researchers have conducted micro/nanotribological
studies of materials and lubricants for use in these devices. Mechanical
properties of nanoscale structures have also been measured. In addition,
component level testing has also been carried out to aid in better understanding
of the observed tribological phenomena in these devices. A fundamental
understanding of nanoscale tribology and mechanics of MEMS/NEMS and BioMEMS/NEMS
is essential as these devices proliferate in the marketplace.
This course provides an introduction to Principles of Nanotribology and
Nanomechanics followed by Applications to MEMS/NEMS and BioMEMS/BioNEMS.

Instructors:
PhD. Mats Halvarsson, Prof. Eva Olsson and Prof. Krystyna Stiller work in the
group for Microscopy and Microanalysis at Chalmers University of Technology in
Sweden. The general aim of the research of the group is to understand how the
microstructure of materials (down to single atoms) influences their properties.
Mats Halvarsson’s main research tools are electron and ion microscopes and their
add-on equipment. His research concerns hard, wear protective coatings produced
by Chemical Vapour Deposition (CVD) and high temperature corrosion of materials
such as Fe-Cr stainless steels, molybdenum disilicides and Fe-Cr-Al alloys.
Eva
Olsson is mainly using advanced analytical microscopy to characterize the
functional microstructure of materials including the characterization of
structure and properties of individual defects. The interfaces are of particular
interest due to their significant influence on properties and microstructural
evolution. The goal is to formulate models with which the physical properties
can be predicted and new devices tailored. The main research tool is analytical
transmission electron microscopy and scanning probe techniques. The research
activities include bulk and thin film oxides (e.g. ZnO, YBa2Cu3O7-x, SrTiO3, Al/AlOx/Al
barriers, La0.67Sr0.33MnO3), photoactive nanostructures (e.g. gold and silver
nanoparticles), magnetic nanoparticles and carbon nanotubes. The research spans
from fundamental research to applied research in collaboration with industry.
Krystyna
Stiller is especially interested in investigations of processes of phase
transformations and high temperature oxidation. Special emphasis of her research
is put to studies of the microstructure and composition of thin surface layers
and grain boundaries. In her studies she uses both transmission electron
microscopy and atom probe analysis. The last mentioned technique enables
investigations of variation in material chemistry on a sub-nanometer scale with
equal sensitivity for all elements. Krystyna Stiller has contributed to the
development of the technique and its applications. She is working closely with
the Swedish industry.
