180-twisted bilayer ReSe as an artificial noncentrosymmetric semiconductor
S. Akatsuka, M. Sakano, T. Yamamoto +18
We have fabricated a 180-twisted bilayer ReSe by stacking two centrosymmetric monolayer ReSe flakes in opposite directions, which is expected to lose spatial invers…
Observation of local atomic displacements intrinsic to the double zigzag chain structure of 1T-MTe2 (M = V, Nb, Ta)
N. Katayama, Y. Matsuda, K. Kojima +7
We describe the existence of local distortion discovered in the synchrotron x-ray single-crystal structure analysis of layered ditelluride 1T-MTe2 (M = V, Nb, Ta). In 1T-TaTe2, the…
Unveiling the orbital-selective electronic band reconstruction through the structural phase transition in TaTe
Natsuki Mitsuishi, Yusuke Sugita, Tomoki Akiba +8
Tantalum ditelluride TaTe belongs to the family of layered transition metal dichalcogenides but exhibits a unique structural phase transition at around 170 K that accompanies t…
Ultrafast Control of Crystal Structure in a Topological Charge-Density-Wave Material
Takeshi Suzuki, Yuya Kubota, Natsuki Mitsuishi +15
Optical control of crystal structures is a promising route to change physical properties including topological nature of a targeting material. Time-resolved X-ray diffraction measu…
