Surface terminations and layer-resolved spectroscopy in 122 iron pnictide superconductors

Ang Li, J. -X. Yin, Jihui Wang +13

The surface terminations of 122-type alkaline earth metal iron pnictides AEFe2As2 (AE = Ca, Ba) are investigated with scanning tunneling microscopy/spectroscopy (STM/STS). Cleaving…
