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…
Unusual surface states associated with the PT-symmetry breaking and antiferromagnetic band folding in NdSb
Asuka Honma, Daichi Takane, Seigo Souma +8
We have performed micro-focused angle-resolved photoemission spectroscopy on NdSb which exhibits the type-I antiferromagnetism below TN = 16 K. We succeeded in selectively observin…
Development of a versatile micro-focused angle-resolved photoemission spectroscopy system with Kirkpatrick-Baez mirror optics
Miho Kitamura, Seigo Souma, Asuka Honma +11
Angle-resolved photoemission spectroscopy using a micro-focused beam spot (micro-ARPES) is becoming a powerful tool to elucidate key electronic states of exotic quantum materials.…
Observation of inverted band structure in topological Dirac-semimetal candidate CaAuAs
Kosuke Nakayama, Zhiwei Wang, Daichi Takane +13
We have performed high-resolution angle-resolved photoemission spectroscopy of ternary pnictide CaAuAs which is predicted to be a three-dimensional topological Dirac semimetal (TDS…
Unusual change in the Dirac-cone energy band upon two-step magnetic transition in CeBi
Hikaru Oinuma, Seigo Souma, Kosuke Nakayama +6
We have performed angle-resolved photoemission spectroscopy (ARPES) on CeBi which undergoes a two-step antiferromagnetic (AF) transition with temperature. Soft-x-ray ARPES has reve…
Evidence for bulk nodal loops and universality of Dirac-node arc surface states in ZrGeXc (Xc = S, Se, Te)
Takechika Nakamura, Seigo Souma, Zhiwei Wang +10
We have performed angle-resolved photoemission spectroscopy (ARPES) on layered ternary compounds ZrGeXc (Xc = S, Se, and Te) with square Ge lattices. ARPES measurements with bulk-s…
