Eighth NanoForum Report: NANOMETROLOGY >> (4.2MB)


New Report on Nanometrology
The concept of nanometrology is introduced and defined in the first part of this report. Its importance is highlighted through an introduction to size – property relationships, which is the key aspect of nanometrology. Nanotechnology and nanosciences exploit and study new phenomena that appear when some characteristic structure of a material is in the nanometre size range. It is obvious that a key element of nanometrology is to measure dimensions in the range 1 to about 100 nm (with precision reaching 0.1 nm nowadays), and to correlate the measured size with properties.
This introduction is followed be a review of European institutions and companies active in nanometrology, which shows that there are not that many organisations involved with nanometrology considering the importance of the field.

Nanometrology standards is an emerging field of nanotechnology, and so in this report some fields are reviewed in more detail. The motivation is to share the experience gathered by the authors with a broad scientific community.

This part of the report concerns in particular:

 determination of size and grain size distribution in nanoparticles and nanomaterials. This field addresses nanostructures with a stochastic component as far as shape and size distribution, which is a considerable challenge for nanometrology. Solutions and procedures regarding how to deal with size characterisation for nanopowders and bulk nanomaterials are presented and open questions explained.

 examples of nanometrology in the nanometre range. This section concerns surfaces and thin films measured with single atom precision.
