Dramatic Changes in the Electronic Structure Upon Transition to the Collapsed Tetragonal Phase in CaFe2As2

R. S. Dhaka, Rui Jiang, S. Ran +7

We use angle-resolved photoemission spectroscopy (ARPES) and density functional theory (DFT) calculations to study the electronic structure of CaFe${}_2$As${}_2$ in previously unexplor…
