Frequency Dependence of the Dielectric Constants and of the Reflectivity for HfO2 and ZrO2 from First-Principles Calculations

Autor: Silva, C. C., Alves, H. W. Leite, Scolfaro, L. M. R.

We present, in this work, our theoretical results for the phonon dispersions and the frequency dependence of the reflectivities and the dielectric constants of ZrO2 and HfO2 in the monoclinic phase. The results show the importance of the lattice cont

Charge and spin distributions in GaMnAs/GaAs Ferromagnetic Multilayers

Autor: Rodrigues, S. C. P., Scolfaro, L. M. R., Leite, J. R., Lima, I. C. da Cunha, Sipahi, G. M., Boselli, M. A.

A self-consistent electronic structure calculation based on the Luttinger-Kohn model is performed on GaMnAs/GaAs multilayers. The Diluted Magnetic Semiconductor layers are assumed to be metallic and ferromagnetic. The high Mn concentration (considere
