Strain and crystal field splitting inversion in III-Nitrides
Fábio D. Bonani, Anderson H. Siqueira, Horácio W. Leite Alves +1
The wurtzite phase group III-Nitrides (AlN, GaN, InN) have attracted great interest due to their successful applications in the optoelectronics since the 90's. In this paper we per…
Ab initio Calculations of the Vibrational Modes of MnAs and Ga1-xMnxAs
H. W. Leite Alves
In this work, we present our theoretical results for the equation of state and the phonon dispersions of MnAs, as well as the Mn concentration dependence of both the lattice parame…
Frequency Dependence of the Dielectric Constants and of the Reflectivity for HfO2 and ZrO2 from First-Principles Calculations
C. C. Silva, H. W. Leite Alves, L. M. R. Scolfaro
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…
Ab initio calculation of the dynamical properties of PPP and PPV
R. L. de Sousa, H. W. Leite Alves
In this work, we have calculated the vibrational modes and frequencies of the crystalline PPP (in both the Pbam and Pnnm symmetries) and PPV (in the P21/c symmetry). Our results ar…
