Awaiting abstract

René Janssen studied Chemistry and Chemical Engineering at Eindhoven University of Technology (TU/e) in the Netherlands where he received his MSc degree in 1983 cum laude and his PhD in 1987. He presently leads the interdepartmental research group on Molecular Materials and Nanosystems at the same school, which is part of the departments of Chemical Engineering and Chemistry, and Applied Physics. In 2011 René was elected member of the Royal Netherlands Academy of Arts and Sciences and in 2013 he was appointed distinguished university professor at TU/e. René Janssen received many awards such as the René Descartes Prize from the European Commission in 2000 and the NWO Spinoza Prize in 2015.

Coffee Break 10:00 AM - 10:30 AM

10:30 AM - 11:00 AM: Can solution-processed organic thin-film transistors enable ubiquitous electronics?

Oana D. Jurchescu, Wake Forest Univ. (United States)

Organic semiconductor devices are expected to become present in many sectors of our lives due to their low-cost, lightweight, versatility and ease of molding into any shape. Their solution processing offers exciting opportunities of incorporating electronics in unconventional technologies that could augment traditional applications. The organic thin-film transistors have been used for decades both as active circuit elements and testbeds for material development. Their performance depends on the organic semiconductor film morphology, quality of the various device interfaces and the device architecture. In this presentation I will discuss the lessons we learned as a field about device design and processing, and the limitations we currently face in optimizing charge injection and transport.

Oana D. Jurchescu is a Baker Professor of Physics at Wake Forest University in Winston-Salem, NC, USA and a fellow of the Royal Society of Chemistry. She received her PhD in 2006 from University of Groningen, the Netherlands, and then was a postdoctoral researcher at the National Institute of Standards and Technology in Gaithersburg, MD. Her expertise is in charge transport in organic and organic/inorganic hybrid semiconductors, device physics and semiconductor processing.

11:10 AM - 11:40 AM: Designing room temperature quantum materials through quantum analog of vibration isolation

Kenan Gundogdu, North Carolina State Univ. (United States)

As the demand for quantum approaches in computing, communication and cryptology is increasing, the need for discovering new “quantum materials” is at an unprecedented level. While for most applications the required quantum properties are known, the designer rules for producing these materials are not clear and quantum materials functioning at room temperature is almost non-existent. Quantum coherence, i.e., the phase stability of a superposition state, is the fundamental requirement for quantum applications. Similarly, macroscopic quantum phenomena such as superconductivity superfluorescence and Bose-Einstein condensation, require a collectively coherent phase in an ensemble. Because quantum phase is extremely fragile under thermal excitations, these phenomena and their utilization in quantum technologies is limited to cryogenic conditions. Based on our recent discovery of room temperature superfluorescence in hybrid perovskites, we believe that it is possible to protect the quantum phase of a quantum system by isolating it from ambient thermal interactions by using a mechanism similar to vibrational isolation in classical mechanical systems. We call this process Quantum Analog of Vibration Isolation-“QAVI”. In this presentation, I will introduce QAVI using our recent experimental results on room temperature superfluorescence in hybrid perovskite thin films, and my perspective for designing quantum materials at high temperatures.

Professor Kenan Gundogdu received his Ph.D. in 2004 from the University of Iowa. He continued his postdoctoral studies at the University of Iowa between 2004-06 and at the Massachusetts Institute of Technology between 2006-08. Since then he has been a faculty member in the physics department at North Carolina State University. Gundogdu’s research program focuses on the investigation of electronic processes in condensed matter systems such as organic and hybrid materials using ultrafast optical spectroscopy. He specifically focuses on understanding material properties that lead to extended electronic coherence in solids and observation of macroscopic quantum states at practically high temperatures.
