Functional Materials and Property Characterization Lab
Machine-translated · View original
A lab that forms and characterizes functional materials, centered on semiconductors.
AboutAbout the lab
Exploring functional materials, from thin films to bulk.
The Functional Materials and Property Characterization Lab forms a variety of functional materials, mainly semiconductors, from thin films to bulk, and evaluates their properties.
Associate Professor Makoto Arita's research themes include the fabrication of functional semiconductor thin films, the evaluation of semiconductor materials using scanning probe microscopy, and the fabrication and evaluation of thermoelectric power generation materials.
Assistant Professor Yoshifumi Ikoma conducts research on semiconductor materials using high-pressure phase transformation, as well as on thin-film formation by chemical vapor deposition.
Key terms
- High-Pressure Phase Transformation
- A phenomenon in which the crystal structure of a substance changes to a different structure when high pressure is applied
- Scanning Probe Microscope
- A microscope that traces the surface of a sample with a fine-tipped probe to examine the surface shape and electrical properties
- Chemical Vapor Deposition
- A method of forming a thin film on a substrate by reacting gaseous raw materials. Also known as CVD
ResearchResearch themes
The lab forms a variety of functional materials, mainly semiconductors, from thin films to bulk, and evaluates their properties using multiple approaches. Its main research themes are the fabrication and "in situ" measurement of functional semiconductor thin-film devices, and the emergence of new properties in semiconductor materials through high-pressure phase transformation.
*Illustrative imageFabrication and Measurement of Semiconductor Thin-Film Devices
The fabrication and "in situ" measurement of functional semiconductor thin-film devices is one of the lab's research themes. Associate Professor Makoto Arita's themes include the fabrication of functional semiconductor thin films and the evaluation of their various properties.
*Illustrative imageNew Semiconductor Materials via High-Pressure Phase Transformation
Bringing out new properties in semiconductor materials through high-pressure phase transformation is one of the lab's research themes. Assistant Professor Yoshifumi Ikoma's themes include the creation of SiGeSn mixed crystals and the elucidation of crystal polymorphs of SiGe and their new properties.
*Illustrative imageNanosemiconductors via Severe Plastic Deformation
The lab studies the production of bulk nanostructured semiconductor materials by severe plastic deformation using High-Pressure Torsion.
*Illustrative imageForming Si-Based Nanofilms by CVD
The lab studies the formation of Si-based nanofilms by chemical vapor deposition using a pulsed supersonic free jet.
