Delicate Ferromagnetism in MnBiTe
Chenhui Yan, Yanglin Zhu, Leixin Miao +9
Tailoring magnetic orders in topological insulators is critical to the realization of topological quantum phenomena. An outstanding challenge is to find a material where atomic def…
Origins of electronic bands in antiferromagnetic topological insulator MnBiTe
Chenhui Yan, Sebastian Fernandez-Mulligan, Ruobing Mei +7
Despite the rapid progress in understanding the first intrinsic magnetic topological insulator MnBiTe, its electronic structure remains a topic under debates. Here we perfo…
Interfacial Electron-Phonon Coupling Constants Extracted from Intrinsic Replica Bands in Monolayer FeSe/SrTiO
Brendan D. Faeth, Saien Xie, Shuolong Yang +10
The observation of replica bands by angle-resolved photoemission spectroscopy has ignited interest in the study of electron-phonon coupling at low carrier densities, particularly i…
3D nature of ZrTe 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 using eV photon energy. We have measured the band structure near the point, and quan…
Ultrafast Electron Dynamics in the Topological Insulator Bi2Se3 Studied by Time-Resolved Photoemission Spectroscopy
Jonathan A. Sobota, Shuolong Yang, Dominik Leuenberger +6
We characterize the topological insulator BiSe using time- and angle- resolved photoemission spectroscopy. By employing two-photon photoemission, a complete picture of the…
Electron propagation from a photo-excited surface: implications for time-resolved photoemission
Shuolong Yang, Jonathan A. Sobota, Patrick S. Kirchmann +1
We perform time- and angle-resolved photoelectron spectroscopy on p-type GaAs(110). We observe an optically excited population in the conduction band, from which the time scales of…
Direct Optical Coupling to an Unoccupied Dirac Surface State in the Topological Insulator BiSe
Jonathan A. Sobota, Shuolong Yang, Alexander F. Kemper +9
We characterize the occupied and unoccupied electronic structure of the topological insulator BiSe by one-photon and two-photon angle-resolved photoemission spectroscopy an…
Ultrafast Optical Excitation of a Persistent Surface-State Population in the Topological Insulator Bi2Se3
Jonathan A. Sobota, Shuolong Yang, James G. Analytis +4
Using femtosecond time- and angle- resolved photoemission spectroscopy, we investigated the nonequilibrium dynamics of the topological insulator Bi2Se3. We studied p-type Bi2Se3, i…
