Low work function in the 122-family of iron-based superconductors

H. Pfau, H. Soifer, J. A. Sobota +8

We determine the work functions of the iron arsenic compounds $A$ Fe $_{2}$ As $_{2}$ ( $A = Ca, Ba, Cs$ ) using photoemission spectroscopy to be 2.7 eV for CaFe $_{2}$ As $_{2}$ , 1.8 eV for…

Mode-selective coupling of coherent phonons to the Bi2212 electronic band structure

S. -L. Yang, J. A. Sobota, Y. He +5

Cuprate superconductors host a multitude of low-energy optical phonons. Using time- and angle-resolved photoemission spectroscopy, we study coherent phonons in Bi $_{2}$ Sr $_{2}$ Ca$_…

Revealing the Coulomb interaction strength in a cuprate superconductor

S. -L. Yang, J. A. Sobota, Y. He +10

We study optimally doped Bi $_{2}$ Sr $_{2}$ Ca $_{0.92}$ Y $_{0.08}$ Cu $_{2}$ O $_{8 + δ}$ (Bi2212) using angle-resolved two-photon photoemission spectroscopy. Three spectral features are res…
