[Aspuru-Guzik group list] Dear group members:

by Alan Aspuru-Guzik

a) If you are part of the EFRC Center for Excitonics: Don't forget to send your updates to Anna as per requested b) If you made a Hardware request to Intel, don't forget to send it to Xavier. Both of them are needed ASAP, as two reports have to go out of the way. With such a large group, the only way to put together reports is this way. Cheers, Alan Alán Aspuru-Guzik | Associate Professor Harvard University | Department of Chemistry and Chemical Biology 12 Oxford Street, Room M113 | Cambridge, MA 02138 (617)-384-8188 | http://aspuru.chem.harvard.edu | http://about.me/aspuru

[Aspuru-Guzik group list] [theochem-announce] Theochem Seminar TODAY, 4pm at Harvard

by Lee-Ping

Dear All, Professor Eric Bittner, from the University of Houston, is presenting a theoretical chemistry seminar TODAY (Wednesday, April 6) from 4:00-6:00pm in the Pfizer lecture hall at Harvard University. Please take note of the location! Title: Bose Einstein condensation of Exciton/Polaritons in organic thin film quantum wells: theory and experimental prospects. Abstract: Recent experiments on thin-film microcavities give evidence of Bose condensation of exciton-polariton states. Inspired by these observations, we consider the possibility that such exotic ``half-light/half matter" states could be observed in thin-film organic semiconductors where the oscillator strength is generally stronger than in inorganic systems. In my talk, I present a theoretical model and simulations of macroscopic exciton-polartiton condensates in anthracene thin films sandwiched within a micro-meter scale resonant cavity and establish criteria for the conditions under which BEC could be achieved in these systems. Thank you!

[Aspuru-Guzik group list] NEW LOCATION for Today's Green Conversations with Jon A. Krosnick

by Center for the Environment

The Harvard University Center for the Environment and Bank of America present Green Conversations with: Jon A. Krosnick Professor, Stanford University “What Americans and Massachusetts Residents Think About Climate Change - Attitude Formation and Change in Response to a Raging Scientific Controversy" Discussants: Stephen Ansolabehere, Professor, Harvard University Department of Government Andrew Hoffman, Holcim Professor of Sustainable Enterprise, University of Michigan; MIT Visiting Professor of Management Moderator: Daniel Schrag, Professor of Earth and Planetary Sciences and Professor of Environmental Science and Engineering; Director, Harvard University Center for the Environment TODAY 5:00 pm UPDATED LOCATION: Science Center A 1 Oxford St. Cambridge, MA Dr. Jon Krosnick, the Frederic O. Glover Professor in Humanities and Social Sciences, and Professor of Communication, Political Science and Pyschology at Stanford, is a social psychologist who does research on attitude formation, change, and effects; the psychology of political behavior; and survey research methods. During the past two decades, many scientific experts have been frustrated by the American public's apparent indifference to climate change and the threats it may pose. And even during the two years, headlines on newspapers across the country have proclaimed: "Scientists and the American Public Disagree Sharply Over Global Warming" and "Public Concern About Climate Waning." Is it really true? Do Americans really not accept the opinions of scientific experts on climate change? In this presentation, Professor Jon Krosnick will describe findings from a series of national surveys that he has designed and conducted since 1996, as well as and a recent survey of Massachusetts residents, tracking what people do and do not believe on this issue and what they do and do not want to have done about it. Surprising results challenge many widely-held presumptions about public opinion, illuminate the increasing politicization of the issue, and provide a context for watching and understanding future efforts to pass (and block) legislation on climate change. Green Conversations are sponsored by the Harvard University Center for the Environment with generous support from Bank of America. Free and open to the public.

[Aspuru-Guzik group list] Please send Hardware requests from Intel -> Please read.

by Alan Aspuru-Guzik

Dear all, For those of you that sent me hardware requests from Intel, I have not had time to collect them. I asked Xavier to do so, so we can send this to Hanspeter Pfister today or early tomorrow. Please as soon as you read this, forward your request in .DOC or similar format to Xavier, preferrably with a figure and references, and he will combine them all.

[Aspuru-Guzik group list] Announcement: Excitonics Seminar, TODAY. April 5, 3 PM/ 36-428

by Cathy Bourgeois

Center for Excitonics Seminar Series Announcement Tuesday, April 5, 2011 3:00 PM RLE Conference Room: 36-428 Charge separation by photoexcitation in semicrystalline polymeric semiconductors: An intrinsic or extrinsic mechanism? Carlos Silva, Université de Montréal Abstract: Understanding charge generation by light absorption in polymeric semiconductors is of profound scientific importance due to the vigorous drive to develop organic solar cells. Confusion prevails with respect to the intrinsic charge photogeneration mechanism in neat (undoped) semicrystalline films. Numerous publications report charge photogeneration yields (the number of electron-hole pairs produced per absorbed photon) up to 30% on sub-picosecond timescales in neat regioregular poly(3-hexylthiophene) films. This is difficult to reconcile with the accepted picture that Frenkel excitons are the primary photoexcitations. Their binding energy is much higher than the lattice thermal energy at room temperature, such that direct charge generation ought to be improbable. Considering this, two fundamental questions arise: (i) what is the mechanism of direct charge photogeneration in semicrystalline polymer semiconductors? (ii) What is the role of solid-state microstructure in defining it? Here, we combine transient photoluminescence and absorption probes and find that charge photogeneration at 10 K occurs continuously over sub-nanosecond timescales, and not by a diffusion-limited exciton dissociation at defect sites. Rather, we conclude that it is an extrinsic process that occurs efficiently by dissociation of excitons localised at interfaces between crystalline and non-crystalline domains, and is driven by interfacial energetic disorder. Bio: Carlos Silva, Canada Research Chair in Organic Semiconductor Materials, is Associate Professor of Physics at the Université de Montréal, having joined the department in 2005. He is the 2010 laureate of the Herzberg Medal of the Canadian Association of Physicists. He has extensive expertise in ultrafast optical probes of electronic dynamics in organic semiconductors with applications in optoelectronics. He obtained a PhD in chemical physics from the University of Minnesota in 1998 and was a Postdoctoral Research Associate in the Cavendish Laboratory of the University of Cambridge from 1998 to 2001. In 2001 he obtained an Advanced Research Fellowship from the UK Engineering and Physical Sciences Research Council, which he undertook at the Cavendish Laboratory. The central theme of his research programme concerns the understanding of electronic dynamics in organic semiconductors using transient photoluminescence and absorption spectroscopies.
