Experimental Condensed Matter Physics
Research Areas
Solid State Spectroscopy (Bum Joon Kim)
Studies solid state quantum materials’ excitations and the dynamics of quasi-particles via light, X-ray, and neutrons. Symmetries of lattice/ magnetic structures are searched by Raman spectroscopies and X-ray/neutron elastic/ inelastic scattering experiments. Of main interest are strongly-correlated materials. Advanced Materials and Extreme Conditions (Jun Sung Kim)
Investigates physical properties of topological matter and magnetic/ superconducting matter in extreme conditions such as extremely low temperature/ high magnetic field/ high pressure. Various synthesis methods are used to create 2D single crystals. Nano-devices fabricated from these crystals are then used to investigate how interesting phenomena occur from topological electronic structures and electronic correlations.Magnetic Probe Microscopy (Jee-Hoon Kim)
Researches non-linear electronic transport properties of topological matter, and realizes metallic transistors by non-linear engineering. Focuses on scanning probe microscopy techniques. Of particular interest are direct imaging of exotic spin structures, as well as the investigation of superconductivity and magnetism under extreme conditions.Scanning Probe Microscopy (Tae-Hwan Kim)
Studies various materials via scanning probe microscopy. By measuring the tunneling current, the local density of states of the sample of interest can be obtained. Main research themes are solitons that exist in 1D charge density waves, 2D van der Waals crystals and graphene.Electron Spectroscopy (Jae Hoon Park)
Artificial Lower Dimensional Electronic Systems (Han Woong Yeom)
Envisions to find new material systems and new physics by combining the new opportunity and the grand problem of low dimensional electronic systems, that is, by combining the topological and materials degrees of freedom with the strong interactions inherent to these electronic systems. In our long-term goal, we hope to develop revolutionary materials and physics, which may lead to a new paradigm in device technology beyond the silicon technology.Quantum Nano-electronics (Gil-Ho Lee)
Fabricates nanoscale hybrid devices from various topological matter, and tests their quantum transport properties at extremely low temperature ( ~10 mK). Collaboration with other competitive research groups are also active.Artificial Complex Oxides (Daesu Lee)
By controlling condensed matter at atomic level, it is possible to find interesting physical properties not easily found in bulk state. This is important in that it can lead to discovering how physical properties of condensed matter systems are related. Here, we synthesize artificial complex oxides to comprehend and predict the nature of condensed matter systems.
