Recent progress in superconductivity of two-dimensional layered systems

Superconductivity in two-dimensional (2D) layered materials is currently one of the most attractive research subjects in solid state physics. One of keys for emergence of superconductivity is a carrier doping. In this symposium, we exchange the information of the superconductivity of carrier- accumulated 2D layered materials and discuss the future perspective.


This symposium will provides the forum of discussion on superconductivity in two-dimensional (2D) layered materials. The superconductivity is currently one of the most attractive and exciting research subjects in solid state physics because many superconductors with high superconducting transition temperatures (T ’s) have been successfully synthesized using the 2D layered materials. c One of keys for emergence of superconductivity is a carrier doping of the 2D layered materials. The carrier doping has been performed not only by chemical methods such as metal-doping and element substitution of precursor material, but also by electrostatic / electrochemical methods. Furthermore, superconductivity which emerges from the interface between two 2D layered materials is also very attractive. Thus, the 2D layered materials have provided a fruitful research stage for realization of superconductivity. In addition to this, the superconducting properties of 2D layered material may provide a very exciting physics from viewpoint of dimensionality and pairing mechanism, in particular the superconductivity of 2D layered materials, which are classified as ‘topological insulator and Weyl semimetal’, is very exciting; the superconductivity often emerges under high pressure.

Special emphasis will be put on the following subjects:

  • Superconductivity produced by metal doping of 2D layered materials 
  • Superconductivity produced by electrostatic / electrochemical carrier doping of 2D layered materials
  • Interface superconductivity in 2D layered materials 
  • Emergence of superconductivity from topological insulator and Weyl semimetal
  • Superconductivity of 2D layered materials under extreme condition
  • Synthesis of new 2D layered materials for superconductivity

Hot topics to be covered by the symposium

  • Interface superconductivity
  • Topological superconductor 
  • Emergence of high-T superconductivity under high pressure c
