CNM Workshop

CNM WK6 (Full Day) Photoinduced Charge Transfer in Nanostructures

Location: Bldg. 401, Room A5000

Organizers: Gary Wiederrecht and Matt Pelton (CNM)

Charge-transfer processes are the first step in the formation of potential energy that moves chemical reactions forward.  Photoinduced charge-transfer processes, in particular, underlie alternative energy technologies such as photovoltaics, solar fuels, and other photocatalytic processes.  Nanoscale structures can exhibit unique charge-transfer properties, and understanding these properties could lead to new and efficient materials for alternative energy technologies. In this workshop, we will explore new phenomena and materials of interest for photoinduced charge transfer that extend over organic, inorganic, hybrid, and biological nanostructures. In addition to exploring new phenomena, advances in energy conversion applications will be presented.
