This weeks image comes from a recent Journal of Physics: Condensed Matter paper by Dr Zhonghao Liu et al. They used angle-resolved photoemission spectroscopy paired with band structure calculations to investigate the electronic structure of KFeCoAs2, which is isoelectronic to the Iron based superconductor BaFe2As2.
Iron based superconductors are of great interest within the condensed matter community, and the exact nature of their electronic structure has been hotly debated. This work shreds valuable light on the global re-normalization and Fermi surface of KFeCoAs2.
