Sekiya Lab
Machine-translated · View original
A solid-state physics lab focused on how the properties of materials change when exposed to light.
AboutAbout the lab
Measuring the light-responsive properties of materials made in-house
Sekiya Lab makes materials with distinctive structures on its own and measures their optical, electrical, and magnetic properties.
The lab also focuses on how properties change when light is applied, hoping that distinctive physical properties will emerge.
Research subjects include single crystals of titanium dioxide, thin films of oxynitrides that are attracting attention as fuel cell catalysts, and light-responsive molecules and dye aggregates.
The lab is said to be open to visits and tours at any time, and visitors are advised to make an appointment whenever possible.
Key terms
- Transition metal oxynitride
- A material attracting attention as an alternative to platinum catalysts at the cathode of polymer electrolyte fuel cells
- Photoinduced magnetization
- A mechanism in which light excites magnetic ions and generates a macroscopic magnetic moment
- Photochromism
- A property in which a substance absorbs light, reversibly changes its structure, and changes color accordingly
ResearchResearch themes
The lab focuses on material systems with distinctive structures and makes the materials it measures itself. It measures their optical, electrical, and magnetic properties and also observes the changes that occur when light is applied, conducting research in the hope that distinctive physical properties will emerge.
*Illustrative imageGrowth of Inorganic Oxide Single Crystals and Their Electronic Properties
Focusing on titanium dioxide-based systems, which are attracting attention as photocatalytic semiconductors, the lab studies them from many angles: growing single crystals, controlling defects, relaxation processes from photoexcited states, and measuring optical properties under ultrahigh pressure.
*Illustrative imageCatalytic Activity of Transition Metal Oxynitride Thin Films
The lab studies depositing transition metal oxynitrides, which are attracting attention as an alternative to platinum catalysts at the cathode of polymer electrolyte fuel cells, directly onto the surface of fine carbon particles by a dry process using sputtering.
*Illustrative imagePhotoinduced Magnetization
Exciting magnetic ions with light into a state whose magnetic quantum number differs from that of the ground state can generate a macroscopic magnetic moment. The lab focuses on RCrO3 (R is a rare-earth metal), which undergoes a transition from antiferromagnetism to weak ferromagnetism, and aims to control magnetization with light.
*Illustrative imagePhotochromism
The lab applies ultrahigh pressure to single crystals of furylfulgide, which isomerizes only under light, to change intermolecular interactions, and investigates the effect of enhanced photoisomerization among multiple stable ground states.
