Nanostructured Materials University of Tsukuba
The properties and applications of amorphous alloys, metallic thin films and nanostructured metals are shown for understanding the unique properties of nanostructured materials.
Lattice defects like point defects, dislocations and interfaces play important roles on macroscopic properties of crystalline materials. The importance become more obvious for nanostructured crystalline materials. The property of amorphous materials, which have no crystalline long-range order but with some short-range order, is another topic in the course. Students should understand how these long-range and short-range orders in the materials contribute on the macroscopic properties of the amorphous materials, thin films and nanostructure materials.
This subject is related to thinking skills that link experimental results with theory.
Intelligibility and learning level will be evaluated using the content of the report (Several problems or assignments are given in the lecture).
