Electronic Functional Materials Lab
Machine-translated · View original
A lab that makes high-quality samples and explores the functions generated by electrons in solids.

AboutAbout the lab
New functions from electrons in solids
The Ikuta Lab experimentally studies physical phenomena produced by electrons in solids.
In particular, it places importance on synthesizing high-quality samples on its own.
The lab measures the properties of the samples it makes, discovers and understands functions not seen before, and ultimately aims to propose them as new materials.
It grows thin films and single crystals of iron-based superconductors and topological materials and investigates their properties.
Key terms
- Iron-based superconductor
- A superconductor containing iron. Discovered in 2008, this family of materials becomes superconducting at temperatures second only to the cuprates.
- Molecular beam epitaxy
- A method of growing a crystalline thin film by evaporating source materials little by little in a vacuum and stacking atomic layers on a substrate.
- Topological insulator
- A material that does not conduct electricity inside but conducts it like a metal only on its surface.
- Dirac semimetal
- A material that has electrons inside it that behave as if they have no mass.

ResearchResearch themes
The lab conducts experimental research on the electronic properties of solids, within solid-state physics. It measures the properties of high-quality samples that it synthesizes itself, with the aim of discovering new functions and proposing them as new materials.
*Illustrative imageThin Films of Iron-Based Superconductors
Iron-based superconductors are attracting attention as the second family of high-temperature superconductors after the cuprates. The lab grows high-quality thin films by molecular beam epitaxy (MBE), and works to elucidate the mechanism of superconductivity and to apply properties unique to iron-based superconductors in electronics.
*Illustrative imageThin Films and Single Crystals of Topological Materials
The lab grows thin films of topological insulators by MBE and pulsed laser deposition (PLD), and works on growing materials that were difficult to obtain as single crystals. It also makes single crystals and thin films of Dirac semimetals, which have Dirac electrons inside the material, and controls their properties by various methods.
