Before the emerging field of organic electronics
can deliver on its commercial promise, however, new measurements,
standards and processing capabilities must be developed. Creating many
of the requisite tools is the aim of a new five-year research effort
at the National Institute of Standards and Technology (NIST).
"Organic electronics is at a stage akin to the very
early days of the silicon semiconductor industry," explains NIST
polymer scientist Eric Lin. "Lack of validated diagnostic probes and
standardized test and measurement methods is an impediment to progress."
Unfortunately, the job of filling this void is
especially challenging. The range of potential materials for organic
electronics--from polymers to nanocomposites--is enormous. The number
of synthesis and processing methods under consideration is also
daunting. Examples include ink-jet printing, roll-to-roll printing and
various ways to coax molecules to self-assemble into components.
Accurate, reliable measurements will help solve
current manufacturing issues and speed widespread use of the new
microchips. Ultimately, says Lin, NIST plans to develop an "integrated
measurement platform." The envisioned tool will allow scientists and
engineers to predict the performance of organic electronic devices
based on composition, structure and materials properties. |
