Experimental Electronic Structure Lab.
In order to understand the electrical properties of a material, it is important to understand the electronic band structure of the material. Using Angle-resolved Photoemission Spectroscopy, an experimental technique that can directly measure the electron band dispersion of surface structures/low-dimensional materials, electron transport laboratories want to understand the electronic structures and topological materials. In particular, it aims to understand the electrical properties of devices made of low-dimensional materials through domestic/foreign joint research on spatially-resolved photoemission spectroscopy (Nano ARPES), which is in the spotlight as a new photoelectron spectroscopy technique.
To carry out this study, a joint study using major domestic and international radiation accelerator facilities is conducted, and a simple level of tight-binding model and density functional theory are calculated in parallel to understand the electronic structure measured by experiments.
