Design of Atomic CrystalsWe are interested in low-dimensional atomic crystals artificially designed at the surface and interface of solids. |
||
Electronic Structures & PropertiesWe study "electronic structures" of low-dimensional atomic crystals to explore new properties and physical phenomena. |
 |
|
 |
Major InstrumentsAngle-resolved photoemission spectroscopy (ARPES) is a powerful technique that probes electronic structures of the designed crystals. |
|
Band-gap EngineeringWe can modulate band gap which is dominantly responsible for electronic properties of materials by means of surface doping. |
 |
|
 |
Topological Field Effect TransistorWe can control the charge or spin conductance by inducing topological phase transition which is possible as we can apply externalelectric field. |
|
Artificial Topological Phase TransitionWe also study the topology of electronic structures of target materials by creating topological phase transition artificially. |

 |
Two-dimensional SuperconductivitySuperconductivity can be realized in two-dimensional systems which we can track by observing the signatures of superconductivity at ARPES spectra. |
