Nanomechanics is the study of the mechanical properties
of material bodies whose dimensions lie in the nanometer
to micrometer scale. Some properties of interest
are Young and shear moduli, shear strength, and work
of adhesion, and yield strength. Tribology involves
the study of friction, wear, and lubrication at sliding
contacts.
 Instruments at LASST that can probe mechanical properties
of surfaces and films include:
UHV AFM Nano-Indentor - combined Atomic Force Microscope
(AFM), Scanning Tunneling Microscope (STM), and Field
Ion Microscope (FIM) in one instrument using a well-defined
probe tip and atomically clean surfaces.
NanoTribometer Metrology System - AFM type force
detection with a high precision metrology stage to
measure forces in the milliNewton range with micrometer
sized sliding contacts
Hysitron Picoindenter - load versus indentation
measurements using a Berkowitch diamond probe and
capacitive force detection
M5 Scanning Force Microscope – used to perform
single line scratch tests and nanometer scale deformation
studies
 Pin-on-Disk Tester - measurements of friction and
wear in circular scratch geometry
Vitrodyne V-1000 microtensile tester - tensile or
compression testing using a 150 gram load cell and
75 mm travel with 1 micron length resolution.
Alpha-Step Surface Profilometer – surface
roughness measured with a diamond stylus over 500
micrometers with 1 nanometer vertical resolution
