Crystal Growth Physics Lab
Machine-translated · View original
A lab that explores crystal growth from the melt through in situ observation.

AboutAbout the lab
Observing crystals as they grow, in situ
The Crystal Growth Physics Lab studies the process by which crystals form from a liquid in which a material has been melted, with a particular focus on melt growth.
Using in situ observation equipment developed in-house, the lab investigates the various phenomena that occur at the boundary between solid and liquid (the solid-liquid interface).
Based on insights from fundamental research, the lab works on developing new, practically useful crystal growth technologies, including growth technology for multicrystalline silicon ingots for solar cells.
On the lab's website, it is introduced under the name “Fujiwara Lab.”
Key terms
- Melt growth
- A method of growing crystals by cooling a liquid material melted at high temperature.
- Solid-liquid interface
- The boundary where the growing crystal (solid) meets the original liquid.
- Ingot
- A large, unprocessed block of material that has been melted and then solidified.
