Panelists
 

Dr. Jesko von Windheim, CEO, Nextreme Thermal Solutions, Inc., will discuss the next generation of thermoelectrics for applications requiring extreme thermal management solutions.

 

Based on its unique, thin-film superlattice technology, Nextreme Thermal Solutions is developing the next generation thermoelectrics for applications that require extreme thermal management solutions.  The technology has the potential to dramatically improve thermal management for the next generation of microprocessors and other integrated circuits. Other applications include refrigeration, personal heating/cooling, power generation, cooling microprocessors, fiber-optic

 

Jesko von Windheim spun Nextreme out of RTI International, where he was Entrepreneur in Residence and VP of Commercialization.  Prior to joining RTI, Dr. von Windheim was responsible for numerous spin-offs from MCNC, Corp. (also a research organization), the most recent of which was Cronos Integrated Microsystems which sold to JDS Uniphase.  At Cronos Dr. von Windheim was VP of Marketing and Business development and he later ran the business unit as General Manager for JDS Uniphase.  Jesko holds a bachelor’s degree in chemistry and physics, a master’s degree and a Ph.D. in physical chemistry, and an MBA from the Kenan-Flagler business school.

Dr. Markus Wohlgenannt, Assistant Professor in the department of Physics & Astronomy at the University of Iowa, will discuss Organic Pi-conjugated semiconductors.

Organic Pi-conjugated semiconductors (OSEC), which are usually divided into the classes of small molecular weight compounds and macromolecular polymers, have been used to manufacture promising devices such as organic light-emitting diodes (OLEDs), photovoltaic cells and field-effect transistors. While studying semi-conducting polymer and small molecule sandwich devices, we discovered a large and intriguing magneto resistance (MR) effect, which we dubbed organic magneto resistance (OMAR). OMAR reaches up to 10% at room temperature for small fields of B =10 mT. OMAR is therefore amongst the largest of MR effects of any bulk material. The devices we describe can be manufactured cheaply on flexible substrates, and may also be transparent. Since the magnitude of OMAR is comparable to GMR, we anticipate OMAR may be used widely in magnetic sensor applications. Our devices therefore hold promise for applications where large numbers of MR devices are needed, such as magnetic read heads, magnetic random access memory (MRAM); and applications related to OLED display screens such as touch screens where the position of a magnetic stylus is detected (patent pending, see demonstration video at http://ostc.physics.uiowa.edu/~wrg/).  Our devices do not require ferromagnetic electrode materials resulting in flexibility in material choice not achievable for other MR devices.

Dr. Markus Wohlgenannt specializes in the field of organic semiconductor devices. He currently works as an assistant professor in the department of Physics & Astronomy at the University of Iowa. He is also the director of the organic semiconductor device research group at the Iowa Advanced Technology Laboratories.  He received his MS degree in physics from the Technical University of Graz in Graz, Austria, and his PhD degree in condensed matter physics from the University of Utah at Salt Lake City. He had previously worked as a research assistant professor in condensed matter physics at the University of Utah, conducting research in the spectroscopy of organic electronic materials, photonic crystals, and also fabrication of organic sandwich devices. His main research interests include spectroscopy and transport in pi-conjugated polymer films and devices, and also extend into molecular physics and physics of low-dimensional semiconductors.
