NEW MATERIALS SCIENCE
JYUN-ICHI YAMAURA LAB.
INTRODUCTION OF LABORATORY
Our laboratory conducts research on structural physics of functional materials. Structural physics is a field that clarifies the properties of materials based on the crystal structures, which are the starting point for materials research. By utilizing not only laboratory systems but also various quantum beams like synchrotron radiation and neutrons from multiple perspectives, we work to understand the fundamentals of the mechanism of functional expression through quantum multi-probe and multi-scale analysis that reveals various aspects of materials on a wide range of atomic scales. We focus on a broad range of topics, including practical materials like dielectrics, semiconductors, and solar cells as well as fundamental materials like new superconductors and magnetic materials. Under the guiding principle of “research that is pleasant to create and measure,” we do our everyday research while taking into account not only how to clarify functions but also how to achieve improved performance.

MESSAGE
TOKYOEXPERIMENTS, IN ANY CASE, ARE ENTERTAINING.
I WANT TO SHARE THE EXCITEMENT OF DISCOVERING A BRAND-NEW PHENOMENON AND KNOWING THAT I CONDUCTED A SUCCESSFUL EXPERIMENT.
I WANT YOU TO HAVE THE BEST TIME POSSIBLE WHILE PERFORMING RESEARCH IN OUR COZY LAB.
I chose to pursue a career in science because I wanted to work in a field where I could utilize my manual dexterity. As a researcher, I was drawn to the thought that I could make beautiful crystals, conduct precise and accurate measurements, and provide correct data.These are the fundamental steps that form the basis of my research. Searching for good crystals can be time-consuming and requires me to spend two to three hours examining them under a microscope. However, when I am fully focused, it becomes easier to find high quality crystals, and the moment I discover one is incredibly satisfying. The feeling of relief when I find “the only one crystal” is what drives my passion for research. Looking back, when I was in elementary school, I used to gaze up at the starry sky during astronomy observations. Later in high school, I observed how metal seeds would grow and form a miniature forest, as well as experiments that would instantly change the color of materials. Perhaps it was the beauty that science can create that drew me to pursue a career in this field.

The Goal of Applied Physics
The goal of Applied Physics is to develop a stage = “new material” that can manipulate undeveloped degrees of freedom, to explore unknown phenomena created from that stage and to bring out excellent functions, and to bring out its excellent functions. The purpose is to contribute to the development of human society by elucidating the mechanisms and developing application fields for these phenomena and functions.
