Abstract
Organic
semiconductors provide the ability to directly manufacture thin
film electronics including transistors, light emitting diodes,
and solar cells. There has been recent interest in using organic
materials as thermoelectrics for conversion of waste heat to
electricity and also temperature control. We will discuss our
efforts to develop methods to control the thermoelectric
properties of semiconducting polymers. In this work, we have
used emerging soft X-ray scattering methods and high resolution
transmission electron microscopy to reveal structural order in
semiconducting polymers to connect nanostructure with
macroscopic properties. Using model systems, we have uncovered
how the process of electrically doping semiconducting polymers
influences their ultimate electrical properties. We will discuss
the current state of performance of organic thermoelectrics and
prospects for the future.

Professor Michael
Chabinyc is Associate Chair of the Materials Department at the
University of California Santa Barbara. He received his Ph.D. in
chemistry from Stanford University and was an NIH postdoctoral
fellow at Harvard University. He
was a Member of Research Staff at (Xerox) PARC prior to joining
UCSB in 2008. His research group studies fundamental properties
of organic semiconducting materials and thin film inorganic
semiconductors with a focus on materials useful for energy
conversion. He has authored more than 150 papers across a range
of topics and is inventor on more than 40 patents. He is
currently an editor of Journal
of Materials Chemistry A.
