"Imaging
Nanostructures in Motion"
|
| Imaging nanostructures with real time microscopy techniques is crucial to developing understanding of the dynamics of the growth of nanostructures and nanostructure arrays. We have combined a high resolution electron emission microscope with the tunable light emission from a free electron laser. We will describe how image contrast is obtained by tuning the wavelength of the free electron laser, and we will present examples of nanostructure dynamics. Images will show nanoscale islands that move together, nanoscale liquid droplets that grow larger as they move, and nanoscale dots that transform to wires. The system can also be used to determine the properties of biological systems, and results on melanosomes will be displayed. Each example represents a complicated physical phenomenon. |
