Q What is your research theme?
Using optical technology and several sharp probes, we aim to advance nanotechnology by creating microscopes that allow us to observe phenomena occurring at ultrahigh speeds with atomic-level detail.
Q What is your research and what attracts you to it?
We mainly conduct research using a device called a “probe microscope,” which allows us to observe the surface of materials using a sharp needle (probe) at the tip, and a pulsed laser, which can emit light for a very short period of time. Our main work is to assemble the devices ourselves and develop the state-of-the-art microscopy equipment and observation methods described above. Recently, we have been focusing on observing/manipulating the movement of electrons and holes (holes through which electrons have escaped) in extremely thin sheets of semiconductor materials, which are expected to be used in information processing devices and other applications, on a nanometer scale. Since we capture weak signals coming from a small part of the needle tip, it is not easy to obtain data, and it is sometimes very difficult. However, I am extremely moved when I obtain results that no one has ever seen before through repeated improvements of the equipment I have built!
What is the future beyond this research and what dreams do you have?
Currently, we are building microscopes to observe extremely minute areas and fast phenomena. In the future, I would like to develop this further and make it possible not only to observe but also to manipulate nanoscale materials. I dream of developing a microscopy technology that will enable me to both create materials and structures at the atomic/molecular level and observe with my own eyes how functions that have never been seen before are being expressed.
Aiming at measurement/manipulation in extreme regions by making full use of pulsed lasers and multiple probes
Q What is the appeal point of the Applied Science and Engineering / Electronics and Physical Engineering subprogram?
I think the greatest feature of this school is the wide range of fields in which students can become involved after entering the school. A wide range of subjects are available, including physics, chemistry, and biology, and guidance is provided by professors who are experts in each of these fields. I am also a graduate of the School of Applied Science and Engineering, but when I entered the university, I could not narrow down the field of study I wanted to pursue in the future. As I recall, I was interested in chemistry at the time I entered the university, but as I learned more I came to enjoy physics, and I eventually entered the doctoral program in the field of physical measurement. The environment of Tsukuba, where many research institutes are concentrated, is also very helpful for me in my research, as it makes it easier for researchers to communicate with each other and to use equipment outside the university.
Q What is your message to students?
I believe that an important part of university life is also to take advantage of that freedom to take your time and take action to determine the field of study you wish to pursue in the future. The School of Applied Science and Engineering is the perfect place for you to do so. By all means, take advantage of Tsukuba’s geographical location and actively challenge yourself in a variety of fields! We will do our best to support you.
Q What are your passions outside of research?
I was a member of a choral group in college, and I still get together from time to time with friends I met there to sing. These days, I am solely absorbed in raising my children.
