“Electron transport in nanocrystal solids and application to infrared photodetection”

Chemistry and physics share tremendous potential at the nm scale, where chemistry excels and where physics predicts that many properties can be tuned.  For example, quantum states, charging, spin, phonons and plasmons show large effects at the nm scale.  Colloidal synthesis has become the enabling science of making nanostructures by chemical precipitation.  I will describe how these techniques enable the development of novel infrared detectors.
