Seeking a Research Scientist or Postdoctral Researcher (W22109)


Emergent Device Research Team
RIKEN Center for Emergent Matter Science
(Team Leader: Yoshihiro Iwasa)

Research Field

The goal of the Emergent Devices Research Team is to pioneer quantum physical properties and functions and using low-dimensional materials, mainly two-dimensional materials, and their nanodevices. In particular, we focus on chalcogenide-based 2D materials and explore their electronic functions through devices such as van der Waals heterostructures, and electric double-layer transistors. We investigate two-dimensional superconductivity, quantum phase control, topological properties, and nonlinear transport phenomena, and create functional materials for highly efficient energy conversion and quantum technologies.

Job title and Job description

Job title

Research Scientist or Postdoctoral Researcher

  • Research Scientist is defined as those with a doctoral degree more than 5 years.
  • Postdoctoral Researcher is defined as those with a doctoral degree of 5 years or less.

*Job judgment will be decided and decided based on applicant's ability, aptitude etc.

Job description

The candidate will conduct experimental studies on two-dimensional (2D) materials, van der Waals heterostructures, moiré superstructures and their devices, to pioneer the cutting edge of quantum properties and functions. Although our team belongs to the supramolecular chemistry area in CEMS, we are seeking for researchers specializing in condensed matter physics for this position.


The candidate should possess a doctoral degree in the condensed matter physics, quantummaterials science, or related fields. Or the candidate will be able to obtain a doctoral degree before the work start date.
