A highlighted paper: JJAP 2022 Spotlights
2022.10.10
A paper published by our graduate student Mr. Uchida (2022 Ms. Eng.) as the first author and Assistant Professor Dr. Soma as the corresponding author has been selected for the 2022 Spotlights of the Japanese Journal of Applied Physics. The Japanese Journal of Applied Physics is an international journal of the Japan Society of Applied Physics (IOP Publishing), in which members of our laboratory regularly participate. The role of Spotlights is to “select and suggest a small number of articles with a high potential for capturing the interest of researchers in the applied physics community.” Access is free upon the selection, so if you are interested, please take a look.
