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…

Band resolved imaging of photocurrent in a topological insulator

Hadas Soifer, Alexandre Gauthier, Alexander F. Kemper +8

We study the microscopic origins of photocurrent generation in the topological insulator Bi $_{2}$ Se $_{3}$ via time- and angle-resolved photoemission spectroscopy. We image the unoccupi…

3D nature of ZrTe $_{5}$ band structure measured by high-momentum-resolution photoemission spectroscopy

H. Xiong, J. A. Sobota, S. -L. Yang +10

We have performed a systematic high-momentum-resolution photoemission study on ZrTe $_{5}$ using $6$ eV photon energy. We have measured the band structure near the $Γ$ point, and quan…
