Summary on Grant Application Form |
|
All materials are made from atoms. We can see atoms In materials using electron microscopes. However, an electron microscope Image is a flat, twodimensional image, just as a photographic image taken using a camera Is a flat two-dimensional image. It is like looking at the world through one eye rather than two. However, there is a special electron microscope technique called tomography that enables us to see the world of atoms in three dimensions. W e are going to develop this technique in this research and apply it to tiny particles called nanoparticles, which we will try to support in the electron microscope using a device called a laser tweezer. This is a very exciting and difficult experiment which has never been done before.The strength of crystals is controlled by defects called dislocations. W e are going to study how the atoms are arranged in dislocations in two important new materials, silicon nitride and gallium nitride. This will help us to understand their properties and to produce better materials. Again, the experiments we propose have not been done before.
