Dopants and Charge Carriers in Colloidal Semiconductor Nanocrystal

Professor Daniel Gamelin
Department of Chemistry
University of Washington

Abstract:  The deliberate introduction of impurities 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 the introduction of open-shell transition metal impurities into the smallest of semiconductor crystallites, semiconductor nanocrystals (quantum dots). The talk will emphasize the use of doping, charging, photoexcitation, and magnetization to generate and manipulate unprecedented physical properties in semiconductors that may impact existing or future semiconductor technologies. The fundamental microscopic origins of these new physical properties will be detailed, and basic aspects of doped semiconductor electronic structures will be discussed in this context.
