The objective of this Seed is to understand cooperative electronic, optical and electromagnetic phenomena emerging from the interactions of nanoscale building blocks. Recent work encompasses synthesis of nanoparticles (figure right) and nanowires, and the investigation of how nanocrystals can drive geometrical rearrangement in polymersome micelles (figure right). A second breakthrough (figure below), developed a ligand exchange process that enables flexible electronic devices (FETs) based on nanocrystal assemblies.
PbS FET on Kapton
We have developed a thiocyanate based ligand exchange process that is compatible with flexible substrates. Kapton films are used as flexible substrates for FETs.
