Research > Condensed Matter Physics

• Physical properties of condensed matters and their application are the subject of both theoretical and experimental researches. The main research areas include ferroelectrics, superconductors, semiconductors, magnetic and multiferroic materials, soft matters and nonlinear effects, low temperature physics, and theoretical solid state physics.
  
  
• Current reaearch topics cover phase transitions in ferroelectric and related materials, theoretical and experimental understanding of the mechanism of high Tc superconductors, integration of superconducting and magnetic materials, electrical and optical studies of rare earth doped silicon based materials, electronic structures of compound semiconductors, mechanisms of blue-green semiconductor lasers, light emitting diodes, structure and physical property studies of soft matters in a mesoscopic scale, nanospinics for spintronic applications, and applications of condensed materials on biomedical and informational technology.
  
  
• In the area of theoretical solid state physics, development of calculational methods for energy calculations using pseudopotential in real space and molecular dynamics simulations as well as the electronic structure of condensed matter in general are being investigated. In addition, analytic theoretical approaches for understanding quantum transport phenomena are being carried out.
  
  
• In the area of nonlinear effects, growth and characterization of nonlinear organic and inorganic crystals, crystal morphology of polar molecules, nonlinear dielectric constants and dynamic chaos are the main topics of research. Surfaces, interfaces, liquid crystal display devices, and defects are also recent concerns in the group.
  
  
• In the area of strongly correlated phenomena, heteroepitaxial growth of transition metal oxide thin films including multiferroics with an atomic precision, high Tc superconductor films on metallic tapes for practical applications, magnetic structural analyses and quantum computations using magnetic resonance, and understanding electronic structures of high Tc superconductors via scanning tunneling spectroscopy are the research topics in the area. Supersolid, critical phenomena, and novel quantum transport properties are being also studied in extremely low temperatures.
