Biography

Shunsuke Sasaki currently works at the Jean Rouxel Materials Institute in Nantes (IMN) as a permanent researcher affiliated to the French National Centre for Scientific Research (CNRS). He earned his bachelor’s degree in polymer chemistry from the Tokyo Institute of Technology in 2014. He continued his studies in organic and polymeric materials at the same institute and completed his Ph.D. research on the design of fluorescent molecules in 2017, under the supervision of Dr. Gen-ichi Konishi. Afterward, he decided to shift his focus to inorganic solid-state chemistry and worked as a JSPS postdoctoral fellow at Nantes University under the guidance of Dr. Laurent Cario and his co-workers at IMN until 2020. He conducted another postdoctoral research at the University of Oxford with Dr. Simon J. Clarke before being recruited by CNRS in 2022. His current research focuses on developing novel low-temperature reactions that enable the tailored design of inorganic solid-state materials with exotic 2D structures.

Biography:

With a Master’s degree in Innovative Materials and Energy Systems, I did my end-of-studies internship at STMicroelectronics in Tours, where I worked on optimizing an etching process for TaN/SiN/TaN capacitors. Currently a PhD student at the Institut des Matériaux Jean Rouxel in the PCM team, my work focuses on the development of electrodes for 3D micro-supercapacitors, using high-power pulse sputter deposition techniques (HiPIMS) and its enhanced variant e-HiPIMS. The aim of this thesis is to optimize the structuring, compliance and electrochemical performance of electrodes (TiN, VN/VOxNy) on 3D substrates to meet high-density energy storage needs in miniaturized systems.
