Mapping Out Three-Dimensional Distributions of Atoms In Materials
Position: Principal Engineer, Electron Microscopy Unit, Materials Fabrication and Analysis Platform, Research Network and Facility Services Division
Q1.What kind of work do you do?
I use equipment such as the 3D Atom Probe (3DAP) and electron microscope to analyze the nanostructure of various materials and devices, as well as maintain these equipment. In particular, the 3DAP is a unique method that allows for the visualization of the distribution of atoms within metals, semiconductors, and insulator materials in three dimensions. I conduct research in collaboration with many companies, research institutions, and universities, both domestic and international, supporting material and device research and development from the perspective of nanostructural analysis.
Q2.When do you feel fulfilled, and what do you find appealing about working at NIMS?
Because NIMS conducts joint research with many companies, you can be closely involved with materials currently finding application in society as well as in the development of novel materials and devices expected to be used in the future. Furthermore, not only is NIMS equipped with a plethora of the world's most advanced experimental equipment, but it also hosts many researchers and graduate students from abroad, allowing you to actively engage in cutting-edge research in an international atmosphere, which is constantly stimulating.
Q3.Can you tell us about what you are currently focusing on?
I am currently focusing on establishing automated fabrication technology for samples for 3DAP and electron microscope analysis. As an engineer, I aim to ‘automate’ my own experience and techniques to enable efficient experimentation and consistently reproducible data collection. While equipment manufacturers are also working on such automation, I want to achieve this kind of automation in sample fabrication from a new perspective based on the knowledge accumulated at NIMS.
Q4.Could you give a message to students aspiring to a technical career?
In the technical realm, you'll be handling various experimental equipment. It's common to encounter problems with this equipment. It's not enough to just learn how to operate it; you need to understand what specifically is happening behind the scenes of those operations. Moreover, experimental devices are constantly evolving. Therefore, it's crucial to strive for understanding to your satisfaction and to keep learning continuously. That said, I too reflect on the need to study more every day.
