The lab explores nanoscale manufacturing that uses atomic diffusion.
AboutAbout the lab
Small-scale manufacturing, made easy for everyone.
The Materials Creation Mechanics Lab studies atomic- and nanoscale manufacturing that uses atomic diffusion, in which atoms move within a solid.
Materials so small they are invisible to the eye show new functions, such as high strength and unusual conductivity, simply by being made small, but they are difficult to make and have not come into widespread use.
The lab is therefore developing new ways to make small materials, such as growing metal nanowires by gathering atoms at targeted locations.
The lab also studies the interaction between electrons and atoms using electron microscopy, and develops methods to improve the mechanical properties of metals and ceramics.
Key terms
- Atomic diffusion
- A phenomenon in which atoms in a solid move and spread when a stimulus is applied. It is the same kind of "diffusion" as ink spreading in water.
- Electromigration
- Atomic diffusion caused by electric current. Flowing electrons push atoms along, and it is known as a cause of failure in electronic packages.
- In situ TEM observation
- A method of observing a sample with a transmission electron microscope while applying stimuli such as an electric field or temperature change.
- Microstructure
- Features such as grain size, crystal orientation, grain boundaries, dislocation density, and phases. It greatly affects the mechanical properties of a material.

ResearchResearch themes
The lab studies technology that uses atomic diffusion, in which atoms move within a solid, to make materials at the nanoscale, where human hands can hardly reach. Alongside developing metal nanowire and metal nanofabrication technologies, it also pursues fundamental research such as the interaction between electrons and atoms and the design of crystal microstructures.
*Illustrative imageMaking metal nanowires by atomic diffusion
Metal nanowires about one-thousandth the width of a human hair are grown like bamboo shoots using diffusion, in which atoms spread within a solid. Atoms are transported by hydrostatic stress fields, electric fields, and temperature fields, and gathered at targeted locations.
*Illustrative imageMetal nanofabrication by atomic diffusion
The lab aims to create technology for freely shaping metal at the nanoscale, like a home 3D printer. Building on its already achieved atom ejection technology, which makes nanowires through atomic diffusion, it explores new fabrication techniques.
*Illustrative imageHow electrons act on atoms and defects
How electrons move atoms and crystal defects, as in electromigration, where an electric current pushes atoms along with the flow of electrons, is not fully understood. Using in situ TEM observation, the lab examines the effects of electrons on defects and atoms.
*Illustrative imageMicrostructure design of metals and inorganic materials
Microstructures such as grain size, crystal orientation, and dislocation density greatly affect mechanical properties such as strength and hardness. Focusing mainly on ceramics, and including metals, the lab explores how to design microstructures.
