Polymer Zwitterions at Semiconductor Interfaces - From Nanocrystals to 2D Surfaces

This talk will describe efforts to augment the properites of nanoscale structures with polymers, especially polymer zwitterions that enable surface binding to nanocrystalline structures or dipole-rich films at planar interfaces. Specific attributes of such soft-hard interfaces to be described will include: 1) boosting photoluminescence quantum yield and temporal stability of photoluminescent nanocrystals; 2) modulating the work function of conducting substrates; and 3) opportuniities to probe polymer structure at precisely at a solid-polymer interface, distinct from that of the surrounding bulk material.
