Nanocrystals as Model Systems for Understanding Structural and Chemical Transformations in the Solid State (Max Planck Lecture)
- Prof. Dr. A. Paul Alivisatos
- Lawrence Berkeley National Laboratory, USA
The advent of means to prepare well-controlled nanoscale building blocks has opened up many new opportunities to understand difficult problems which lie at the core of materials science. As an example, nanometer-size inorganic nanocrystals can be transformed from one state to another with remarkably simplified kinetics compared to extended or bulk solids.
This talk will present results on the nanoscale kirkendall effect, on cation exchange in nanocrystals, and shock-wave studies of structural transformations in nanocrystals, In each one, fundamental impact of the transformations, whichare obscured in bulk experiments, can be more reliably observed and understood in the case of nanocrystals.
