Ferromagnetism makes a doped semiconductor less shiny
F. P. Mena, J. F. DiTusa, D. van der Marel +5
Magnetic semiconductors have attracted interest because of the question of how a magnetic metal can be derived from a paramagnetic insulator. Here our approach is to carrier dope i…
From Mott insulator to overdoped superconductor: Evolution of the electronic structure of cuprates studied by ARPES
A. Damascelli, D. H. Lu, Z. -X. Shen
We review our angle-resolved photoemission spectroscopy (ARPES) results on different layered oxide superconductors, and on their insulating parent compounds. The low energy excitat…
Fermi surface of Sr2RuO4 from angle resolved photoemission
A. Damascelli, K. M. Shen, D. H. Lu +9
We investigated the low-energy electronic structure of Sr2RuO4 by angle-resolved photoemission spectroscopy (ARPES) focusing, in particular, on the controversial issues of the Ferm…
n(k) Structure and Matrix Elements in Photoemission: Results from Insulating Ca_2CuO_2Cl_2
F. Ronning, C. Kim, K. M. Shen +5
The photon energy dependence of angle-resolved photoemission data on Ca_2CuO_2Cl_2 is presented, and the role of the matrix element is investigated. It is shown that despite strong…
Inversion symmetry in the spin-Peierls compound NaV2O5
A. Meetsma, J. L. de Boer, A. Damascelli +3
At room-temperature NaV2O5 was found to have the centrosymmetric space group Pmmn. This space group implies the presence of only one kind of V site in contrast with previous report…
