Abstract:

Pi-conjugated organic molecules and polymers now provide a set of well-performing semiconductors that support a wide range of devices, including light-emitting diodes (LEDs) as used in smart-phone displays, field-effect transistors (FETs) and photovoltaic diodes (PVs).  These are attractive materials to manufacture, particularly for large-area applications where they be processed by direct printing.   In this talk I will illustrate those aspects of the physics of their electronic properties that distinguish them from inorganic semiconductors, and that have required specific engineering of material and device design.
