Photoemission angular distribution beyond the single wavevector description of photoelectron final states
Hiroaki Tanaka, Shota Okazaki, Yuto Fukushima +9
We develop a simulation procedure for angle-resolved photoemission spectroscopy (ARPES), where a photoelectron wave function is set to be an outgoing plane wave in a vacuum associa…
Time-, spin-, and angle-resolved photoemission spectroscopy with a 1-MHz 10.7-eV pulse laser
Kaishu Kawaguchi, Kenta Kuroda, Z. Zhao +12
We describe a setup of time-, spin-, and angle-resolved photoemission spectroscopy (tr-SARPES) employing a 10.7-eV (=115.6 nm) pulse laser at 1-MHz repetition rate as a probe ph…
Spin-polarized saddle points in the topological surface states of the elemental Bismuth revealed by a pump-probe spin-resolved ARPES
Yuto Fukushima, Kaishu Kawaguchi, Kenta Kuroda +11
We use a pump-probe, spin-, and angle-resolved photoemission spectroscopy (ARPES) with a 10.7 eV laser accessible up to the Brillouin zone edge, and reveal for the first time the e…
A robust weak topological insulator in a bismuth halide Bi4Br2I2
Ryo Noguchi, Masaru Kobayashi, Kaishu Kawaguchi +11
We apply a topological material design concept for selecting a bulk topology of 3D crystals by different van-der-Waals stacking of 2D topological insulator layers, and find a bismu…
