Sessler Lectureship: Professor Daniel R. Gamelin, University of Washington
About the Seminar:
"Dopants and Charge Carriers in Colloidal Quantum Dots"
The deliberate introduction of impurities and charge carriers into semiconductors can completely transform their physical properties in ways that are essential to their performance in information processing devices, solar cells, injection lasers, and numerous other semiconductor technologies. This talk will focus on our group's exporation of the properties of the smallest of semiconductor crystallites, semiconductor nanocrystals (quantum dots), following introduction of open-shell transition metal impurities, aliovalent impurities, or charge carriers. The talk will emphasize the use of doping, charging, photoexcitation, and magnetization to generate and manipulate physical properties in ways that may inform or impact nascent semiconductor nanocrystal technologies. The fundamental microscopic origines of these new physical properties will be detailed, and basic aspects of doped semiconductor electronic structures will be discussed in this context.
About the Speaker:
Daniel R. Gamelin received his B.A. in chemistry from Reed College, spent a year as a visiting scientist at the Max-Planck Institut fur Strahlenchemie, and earned his Ph.D. in chemistry from Stanford University working with Edward I. Solomon in the fields of inorganic and bioinorganic spectroscopies. Following a postdoctoral appointment with Hans. U. Gudel (University of Bern) studying luminescent inorganic materials, he joined the chemistry faculty at the University of Washington, Seattle (2000), where he presently holds the Harry and Catherine Jaynne Boand Endowed Professorship in Chemistry. He spent 2007-2008 as a visiting professor at the University of Konstanz Center for Applied Photonics and the Ecole Polytechnique Federale de Lausanne (EPFL).
His current research involves the development of new inorganic materials with unusual electronic structures that give rise to desirable photophysical, photochemical, magnetic, or magneto-optical properties. Prof. Gamelin's recent honors include election as a Fellow of the American Association for the Advancement of Science (AAAS), receipt of the American Chemical Society DIC Inorganic Nanoscience Award, the Dalton Lectureship in Inorganic Chemistry, the Presidential Early Career Award for Scientists and Engineers (PECASE), a Sloan Research Fellowship, a Camille Dreyfus Teacher-Scholar Award, a Cottrell Scholar Award, election as a Senior Fellow of the Zukunftskolleg at the University of Kostanz, and selection as a Scialog Fellow of the Research Corporation. He is presently an associate editor for the journal Chemical Communications (Royal Society of Chemistry).
