(100) ideal-surface band structure for the series of Cu-based chalcopyrites
H. Tototzintle-Huitle, R. Baquero
We use the Surface Green Function Matching (SGFM) method and a tight-binding hamiltonian to calculate the (100)-surface electronic band structure and local density of states of the…
Influence of distortion on the electronic band structure of CuInSe2
H. Tototzintle-Huitle, J. Otalora, J. A. Rodriguez +1
We present a tight-binding calculation of the influence of distorsion on the bulk electronic structure of the chalcopyrite CuInSe2. We calculate the ideal case and then the effect…
Ferromagnetism in a (001), (110), and (111)-oriented Ru mololayer on Ag, Au, and Cu-substrates
L. M. Garcia-Cruz, A. V. Gaftoi, A. Rubio-Ponce +2
We have studied the magnetic behavior of a 4d transition metal Ru monolayer (ML) on different substrates and orientations. In the ground state, a Ru-ML is expected to be ferromagne…
Van Hove Singularities around the Fermi level in YBa2Cu3O7: The importance of the chains
A. Rubio-Ponce, R. Baquero
We have reproduced band structure calculations from the literature and have used them to analyze in detail the energy landscape around the Fermi level. We found three Van Hove sing…
