Variation of strong correlation effects in A-site ordered perovskites CaCu3Ti4-xRuxO12: Photoemission and inverse photoemission studies
H. J. Im, M. Iwataki, M. Tsunekawa +4
We have systematically studied the strong correlation effects in A-site ordered perovskites CaCu3Ti4-xRuxO12 (x = 0, 1, 3.5, and 4) by using photoemission and inverse photoemission…
Growth and Raman spectroscopy of thickness-controlled rotationally faulted multilayer graphene
H. Kato, N. Itagaki, H. J. Im
We report the growth of thickness-controlled rotationally faulted multilayer graphene (rf-MLG) on Ni foils by low-pressure chemical vapor deposition and their characterization by m…
Electronic structure of Mott-insulator CaCu3Ti4O12: Photoemission and inverse photoemission study
H. J. Im, M. Iwataki, S. Yamazaki +10
We have performed the photoemission and inverse photoemission experiments to elucidate the origin of Mott insulating states in A-site ordered perovskite CaCuTiO (CCT…
Strong Correlation Effects of A-site Ordered Perovskite CaCu3Ti4O12 revealed by Angle-Resolved Photoemission Spectroscopy
H. J. Im, M. Tsunekawa, T. Sakurada +8
We report angle-resolved photoemission spectroscopy (ARPES) results of A-site ordered perovskite CaCuTiO. We have observed the clear band dispersions, which are shif…
Fermi Surface Variation of Ce 4f-electrons in Hybridization Controlled Heavy-Fermion Systems
H. J. Im, T. Ito, H. Miyazaki +6
Ce 3d-4f resonant angle-resolved photoemission measurements on CeCoGeSi and CeCoSi have been performed to understand the Fermi surface topology as a function…
