Enhancement of the thermoelectric properties in bilayer graphene structures induced by Fano resonances
J. A. Briones-Torres, R. Pérez-Álvarez, S. Molina-Valdovinos +1
Fano and hybrid resonances of bilayer graphene could be attractive for thermoelectric devices. The special profile presented by such resonances could significantly enhance the Seeb…
Relations between transfer matrices and numerical stability analysis to avoid the problem
R. Pérez-Álvarez, R. Pernas-Salomón, V. R. Velasco
The transfer matrix method is usually employed to study problems described by equations of matrix Sturm-Liouville (MSL) kind. In some cases a numerical degradation (the so call…
Electron-phonon deformation potential interaction in core-shell Ge-Si and Si-Ge nanowires
Darío G. Santiago-Pérez, C. Trallero-Giner, R. Pérez-Álvarez +2
We settle a general expression for the Hamiltonian of the electron-phonon deformation potential (DP) interaction in the case of non-polar core-shell cylindrical nanowires (NWs). On…
Polar optical phonons in core-shell semiconductor nanowires
Darío G. Santiago-Pérez, C. Trallero-Giner, R. Pérez-Álvarez +1
We obtain the the long-wavelength polar optical vibrational modes of semiconductor core-shell nanowires by means of a phenomenological continuum model. A basis for the space of sol…
Transfer Matrices and Green Functions for the study of elementary excitations in multilayered heterostructures
R. Perez-Alvarez, F. Garcia-Moliner
This article is concerned with a mathematical tool, the Associated Transfer Matrix T, which proves useful in the study of a wide class of physical problems involving multilayer het…
Symmetries and General Principies in the Multiband Effective Mass Theory: A Transfer Matrix Study
L. Diago-Cisneros, H. Rodriguez-Coppola, R. Perez-Alvarez +1
We study the time reversal and space inversion symmetry properties of those transfer matrices mostly used in the calculation of energy spectra and transport-process. We study the t…
