 Electronics go Organic
from SSRL Headlines
Using SSRL beamlines 11-3 and 10-1, a team of researchers including
Stanford Synchrotron Radiation Laboratory scientists and Stanford
University researchers, have determined the precise arrangement of
molecules within a thin film sample of an organic semiconductor, a step
that could soon help scientists better design these materials. The
results appear in the March 19 issue of the Journal of the American Chemical Society.
Although well-understood, traditional silicon semiconductors are costly to manufacture, making large arrays of efficient solar arrays, for example, expensive. Organic semiconductors represent a potential source of inexpensive electronics that may one day be used to make solar cells, LCD displays and electronic paper.
Using Near Edge X-ray Absorption Fine Structure (NEXAFS) and Grazing Incidence X-ray Diffraction, the team examined thin-film samples of the organic, or "plastic," semiconductor material called thiotetracene, which was first reported by Prof. Zhenan Bao's group. Results obtained using the two techniques to determine the molecular arrangement of the semiconductor gives researchers a better understanding of how the molecular structure of the material relates to its electronic properties, paving the way for greater control over manufacturing such materials.

Stanford Summer Science Lecture Series
by Kaye Storm
Stanford's Office of Science Outreach invites the Stanford community and general public to campus this summer for four Thursday evenings filled with the wonders of art and science! Come in the late afternoon to visit the acclaimed Cantor Arts Center, then enjoy dinner at the Cool Café or bring a picnic. Settle into chairs that will be provided or bring your own lawn chairs
and picnic blankets and hear Stanford's top scientists talk about their research in terms you will understand. Lectures begin at 7:00 p.m. on July 10, July 24, August 7 and August 21.
The 2008 Stanford Summer Science Lecture Series topics and faculty speakers include:
• Why is Earthquake Prediction so Difficult? with Gregory C. Beroza, July 10
• Global Warming: Is the Science Settled Enough for Policy? with Stephen Schneider, July 24
• Wired for Speech: How Voice Activates Interactions with People and Computers with Clifford Nass, August 7
• Powering the Future with Sustainable Energy with Stacey F. Bent, August 21
More information can be found on the
Stanford website.
