- This project is to educate students about important roles of electron
microscopy in nanoscience and nanotechnology. It will cover some properties of
electrons, principles of electron microscopy, applications of electron
microscopy in characterizing nano-scale materials, and the development of
electron microscopy to meet challenges in nanotechnology.
- Electron microscopy normally refers to scanning electron microscopy (SEM)
and transmission electron microscopy (TEM), including tens of special
techniques. Nano-structured materials includes 0 to 3 dimensional nanometer
scale structures such as nano-particles, nanowires, interfaces and multilayers.
Electron microscopy not only let students see a real nano-word, but also
provides other varieties of information such as composition, crystal structure,
and electronic structure.
- The project will lead students to the nano-world. The knowledge they gain
from this project will greatly benefit them in their career and future
Key modern technologies, for example, television, computer, flash memory for
digital camera results from the knowledge we have gained from electrons. It is
hardly to think what our daily life looks like without electrons.
