Global  Research Effort into NanoScale Strain Measurements

Aninternational research collaboration is aiming to drive innovation in electronic devices through deliver y of highly accurate measurements of strain in materials at the nano-scale level. The European Metrology Research Programme’s Nanostrain  project  is backed by national measurement institutes such as the National Physical Laboratory and the Physikalisch-Technische Bundesanstalt, with industry support from the likes of IBM and Polytec.

The consortium will be particularly focusing on piezoelectric materials  that change their shape in response to electric voltages, with the aim of advancing commercial opportunities . This includes the development of the first Piezoelectric-Effect-Transistor (PET), a new digital switch with the potential to offer increased speed, reduced micro-chip size and lower power consumption.

Advances here would overcome a decade of stagnation in semiconductor transistor performance which has seen computational processing power fail to increase by more than a few percent since 2003.

The three year Nanostrain project brings together several European national laboratories along with a consortium of collaborators including world class research instrument facilities at the ESRF and nine commercial companies spanning a wide range of applications.

The project will develop new tools for the characterisation of nano-strain under industrially relevant conditions of high stress, and electric fields. The results will then be openly available to manufacturers and designers to encourage innovation across a wide range of industries.

Prof Markys Cain, Nanostrain project lead at NPL said: “This is a completely unique collaboration, unparalleled in terms of its collective expertise in the areas of material science, metrology and the properties and performance of piezoelectric systems. It’s an exciting project to be involved in as it won’t be simply going over old ground or providing a minor improvement on what already exists. Currently there is no metrological framework or facilities for traceable measurement in this area. This is high risk, challenging work that will underpin a major step change in the performance of devices we use every day and bring highly influential new technologies to market in diverse sectors such as microelectronics, ICT, 3D printing and sensors industries.”

Dr. Burkhard Beckhoff at PTB said: “Europe is particularly well positioned to benefit from new electronic components such as transistors and memory devices based on nanoscale functional materials, with a strong technology-driven manufacturing sector and a vibrant community of innovative companies. Through Nanostrain we hope to establish the metrological and material science foundations  in Europe from which our ICT, bio-medical, sensors and instrumentation sectors can innovate and lead the world in the future.”

Dr Glenn J. Martyna at IBM said: “Computer clock speeds have remained frozen since 2003, limiting not only innovation in new electronics, but also in global efforts to improve energy efficiency and reduce power consumption within the electronics sector as a whole. However with our latest calculations suggesting piezoelectronic transistors can operate at one-tenth of the voltage of today’s CMOS equivalent, consuming 100 times less power as they do so, we believe we are on the verge of a major breakthrough. The next steps include improving our understanding of how this technology could best work in practise, and that relies on a better understanding of how these nano-scale piezoelectric materials strain in order to optimise their commercial performance. We are excited to be part of the EMRP Nanostrain project because we believe this impressive collection of organisations and expertise can deliver this important final step towards long-awaited fast processing speeds.”
