Automated end-station at the soft X-ray beamline featuring robotic air-to-ultrahigh-vacuum sample transfer, scanning probe spectroscopy, and machine learning analysis
Keita Hiromori, Masashige Miyamoto, Masafumi Horio +4
Driven by the growing integration of artificial intelligence and robotics in experimental science, we redefine the execution of user experiments at synchrotron soft X-ray beamlines…
Quasi-One-Dimensional Electronic Nature of Ta4SiTe4 Underlying the Giant Thermoelectric Performance
Hironari Isshiki, Ayumu Tabata, Masafumi Horio +13
Ta4SiTe4 is a one-dimensional van der Waals material that exhibits an exceptionally large thermoelectric power factor below room temperature. However, since this material has been…
Surface structure of the 3x3-Si phase on Al(111), studied by the multiple usages of positron diffraction and core-level photoemission spectroscopy
Yusuke Sato, Yuki Fukaya, Akito Nakano +13
The structure of an Al(111)3x3-Si surface was examined by combining data from positron diffraction and core-level photoemission spectroscopy. Analysis of the diffraction rocking cu…
Non-equilibrium pathways to emergent polar supertextures
Vladimir A. Stoica, Tiannan Yang, Sujit Das +31
Ultrafast stimuli can stabilize metastable states of matter inaccessible by equilibrium means. Establishing the spatiotemporal link between ultrafast excitation and metastability i…
Surface-state Coulomb repulsion accelerates a metal-insulator transition in topological semimetal nanofilms
S. Ito, M. Arita, J. Haruyama +11
The emergence of quantization at the nanoscale, the quantum size effect (QSE), allows flexible control of matter and is a rich source of advanced functionalities. A QSE-induced tra…
