Introduction
Atomic force microscopy (AFM) is
a sub-nanometer scale imaging and
measurement tool that can be used to
determine a sample’s surface topology
and measure its mechanical properties.
AFM imaging relies on a small AFM probe
that is raster scanned over a surface to
generate an AFM image. As shown in
fi gure 1, AFM probes have two major
components; a fl exible cantilever, which
is attached to the probe chip, and a sharp
probe tip near the end of the cantilever.
The cantilevers generally have either
triangular or rectangular geometries.
AFM probes can be manufactured from a
variety of materials, but most are made of
silicon and/or silicon nitride (Si3N4).
