Kenta Arima, Professor

The Nano Surface and Interface Engineering Lab (Arima Lab) studies how to understand and control, at the atomic and molecular level, interactions at solid–liquid and solid–gas interfaces. Using microscopes that can image the arrangement of atoms, spectroscopic analysis that probes the very thin outermost layers of a surface, and simulations based on quantum mechanics, the lab works on ultra-precision surface measurement. The lab is also creating high-performance semiconductor nanomaterials by making use of novel etching phenomena, and developing new surface processes. Established in April 2023, it is a relatively new lab, and aims to contribute to the future of manufacturing, including the creation of next-generation green devices.

The Advanced Device Engineering Lab (Watanabe Lab) aims to create devices with innovative functions, starting from materials design and by combining dissimilar materials and adopting new structures. The lab covers every stage of materials, processes, and devices in a continuous line, from elucidating the fundamental physical properties of semiconductors and controlling defects to fabricating devices, analyzing operating principles, and demonstrating high performance and high reliability. Research topics include power electronics, which is essential for realizing an energy-saving society, and next-generation quantum devices that will open the way to ultrafast computing and perfectly secure communication. Researchers can use process equipment in a Class 1 cleanroom, measurement and analysis tools, and a high-performance supercomputer.

The Atomic Process Control Lab studies how to control “manufacturing” in the nanometer world by observing and manipulating the world of atoms and molecules, working with organic molecules and carbon materials. The lab develops new instruments that precisely measure the minute physical and chemical quantities associated with phenomena in the tiny world, and uses the knowledge gained to develop devices based on new concepts. Research is carried out by three groups: one that investigates molecular structure and optical activity with a scanning tunneling microscope (STM), one that combines synchrotron radiation with STM, and one that studies structural color inspired by the Morpho butterfly. The lab's website states that it is recruiting curious students, regardless of their field of specialization at the time of admission.

The Functional Materials Lab studies the development of thin-film deposition technology using atmospheric-pressure, very-high-frequency plasma, and its application to novel devices. By making use of the physical and chemical properties of plasma, the lab aims for low-temperature, high-speed, high-quality, eco-friendly and clean film deposition. The lab names novel functional devices such as high-performance solar cells, thin-film transistors, and highly sensitive sensors as target applications. On the lab's website, it is introduced under the name "Yasutake Lab."
Kazuya Yamamura, Distinguished Professor

The Nanomanufacturing Science Lab (Yamamura Lab) studies processes that machine material surfaces using atmospheric-pressure plasma and electrochemical reactions. The atmospheric-pressure plasma processes consist of plasma CVM for shaping, plasma-assisted polishing for surface finishing, and surface treatment to improve the adhesion of resins. The lab also works on a polishing method for conductive, hard, and brittle materials such as SiC, in which the surface is softened by anodic oxidation and then removed with soft fixed abrasives. This lab is located in the Research Center for Precision Engineering, which is affiliated with the Graduate School of Engineering at Osaka University.

The Computational Physics Lab combines fundamental principles of physics, such as quantum mechanics and statistical mechanics, with machine learning to investigate the properties of materials through calculation. The lab aims to clarify the mechanisms behind electrical, magnetic, optical, chemical, and mechanical properties, and to theoretically design materials with desirable properties. It focuses on developing materials important for industrial development and for energy and environmental issues, working on topics such as catalysts that convert carbon dioxide and the machining of diamond. On the lab's website, it is introduced under the name "Morikawa-Hamada Lab."
Yasuhisa Sano, Professor

The Ultraprecision Machining Lab (Sano Lab) studies machining methods that create surfaces with atomic-scale accuracy, and X-ray instruments that use them. Using reactive species in plasma and reactive nanoparticles in solution, the lab has established techniques that shape surfaces to within 0.5 nanometers of error and finish the surfaces of X-ray mirrors and semiconductor substrates. In joint research with the Optics Group at SPring-8 (RIKEN), the lab is developing an ultra-high-resolution scanning X-ray microscope and X-ray micro-CT. The lab has also begun applied research on its newly developed X-ray instruments in collaboration with fields such as medicine, biology, and pharmaceutical science.

The Quantum Measurement Lab uses its original ultrasound and optical measurement techniques to study nanomaterials and biomolecules and to develop new devices. The ultrasound frequencies it works with span a wide range, from 20 kHz to 1 THz, and the target materials vary as well. The lab works on protein quantification devices that contribute to diagnosis and drug discovery, research on applying force to cells, and sensors for assessing the structural health of social infrastructure. On the lab's website, it is introduced under the name "Ogi Lab."

The Mathematical Systems Science Lab studies systematization and its applications using mathematical science approaches such as mathematical programming and statistical methods. Through modeling of corporate production activities and of social and natural phenomena, and through system analysis based on the science of uncertainty, the lab aims to cultivate systematization skills. The lab belongs to the Department of Information and Physical Sciences, Graduate School of Information Science and Technology, Osaka University, and undergraduate students from the School of Engineering's Department of Applied Science also join as members. The lab welcomes applicants from other universities and other faculties, and accepts lab visits at any time.

The Terahertz Science Group (Arikawa Lab) studies electromagnetic waves in the terahertz region, which lies between radio waves and light. Using both electronics and photonics technologies, and building on a deep understanding of fundamental physics, the lab aims to create new principles and technologies for generating, detecting, controlling, and using terahertz waves. The research results will be extended to next-generation wireless communications and high-performance sensing.
