Materials Microstructure Lab
Machine-translated · View original
The lab develops new materials by observing and manipulating atoms with electron microscopes.
AboutAbout the lab
Electron microscopes that observe, manipulate, and measure atoms.
The Materials Microstructure Lab develops metals, ceramics, semiconductors, and composite materials based on electron microscopy.
Experiments center on fabricating materials, examining their microstructure with a transmission electron microscope, and evaluating their physical properties.
The lab also develops electron microscopes that can manipulate the arrangement of atoms in a material while observing it, and even measure its properties.
Key terms
- Electron microscope
- A microscope that uses electron waves and electron lenses to magnify objects too small to be seen with an optical microscope
- CFRP
- Carbon fiber reinforced plastic. It is used in materials for next-generation aircraft and engines
- Atomic wire
- The ultimate microstructure, formed by single metal atoms lined up one by one in a row
ResearchResearch themes
The lab uses electron microscopes to study cutting-edge materials such as metals, semiconductors, ceramics, and CFRP. Experiments center on materials fabrication, microstructure analysis by transmission electron microscopy, and property evaluation, and the lab also places strong emphasis on developing new research methods.
*Illustrative imageMaterials for aircraft and engines
Targeting CFRP, heat-resistant alloys, and ceramics used in aircraft and engines, the lab creates harsh conditions such as mechanical loads and extremely high temperatures inside an electron microscope. It directly observes the microstructure of the materials under these conditions and applies the findings to materials development.
*Illustrative imageAtomic-scale metal devices
The lab fabricates tiny metal devices such as atomic wires and metal contacts with cross-sections only a few atoms wide, and investigates their structure, electrical conduction, strength, and other properties. A distinctive feature of atomic wires is that their electrical conductance can be freely controlled.
*Illustrative imageAtomic motion in deformation, friction, and wear
The lab conducts experiments to clarify, at the atomic level, mechanical interactions in structural materials such as deformation, friction, and wear. Using methods unique to the lab, it directly observes the motion of atoms in minute regions only a few atomic layers thick.
*Illustrative imageNanostructured devices that generate power and light
The lab develops new devices made of metals, ceramics, and carbon materials a few nanometers or only atoms in size. Possible applications include power generation from sound waves, vibration, and heat at room temperature, as well as light-emitting devices. The lab also studies carbon nanotubes and graphene.
