    • Sn-doped CdTe as promising intermediate-band photovoltaic material 
      Flores, Mauricio A.; Menéndez Proupin, Eduardo; Orellana, Walter; Peña, Juan L. (Institute of Physics, 2017)
      The formation energies, charge transition levels and quasiparticle defect states of several tin-related impurities are investigated within the DFT + GW formalism. The optical spectrum obtained from the solution of the ...
    • Study of isolated point charge defects in CdTe by Ab-Initio calculations 
      Casanova Páez, Marcos Andrés (Universidad de Chile, 2017)
      La generación de energía a través de la radiación solar es una de las tecnologías más prometedoras para un futuro sustentable. En particular, las tecnologías fotovoltaicas de telururo de cadmio (CdTe) aún se encuentran ...
    • Symmetry and thermodynamics of tellurium vacancies in cadmium telluride 
      Menéndez-Proupin, E.; Casanova-Páez, M.; Montero-Alejo, A. L.; Flores, M. A.; Orellana, W. (Elsevier B.V., 2019)
      The equilibrium geometries and thermodynamic properties of anion vacancies in cadmium telluride, as predicted by density functional theory, are revisited using semilocal and hybrid density functionals. We find that stable ...
    • Tellurium vacancy in cadmium telluride revisited: Size effects in the electronic properties 
      Menéndez Proupin, Eduardo; Orellana, W. (Wiley & Sons, 2015)
      The quantum states and thermodynamical properties of the Te vacancy in CdTe are addressed by first principles calculations, including the supercell size and quasiparticle corrections. It is shown that the 64-atoms supercell ...
