    • A model for defect formation in materials exposed to radiation 
      Davis, Sergio; González Cataldo, Felipe Andrés; Gutiérrez Gallardo, Gonzalo Javier; Avaria, Gonzalo; Bora, Biswajit; Jain, Jalaj; Moreno, José; Pávez, Cristian; Soto, Leopoldo (American Institute of Physics, 2021)
      A simple model for the stochastic evolution of defects in a material under irradiation is presented. Using the master-equation formalism, we derive an expression for the average number of defects in terms of the power flux ...
    • Growth of ni nanoclusters on irradiated graphene: a molecular dynamics study 
      Valencia, F.; Hernández-Vázquez, E. E.; Bringa, E. M.; Morán López, J. L.; Rogan Castillo, José; González, R. I.; Muñoz, F. (The Royal Society of Chemistry, 2018-06-28)
      We studied the soft landing of Ni atoms on a previously damaged graphene sheet by means of molecular dynamics simulations. We found a monotonic decrease of the cluster frequency as a function of its size, but few big ...
    • Positron annihilation studies on chemically synthesized FeCo alloy 
      Rajesh, P.; Sellaiyan, S.; Uedono, A.; Thirumurugan, Arun; Joseyphus, R. Justin (Nature Publishing, 2018-06-27)
      Equiatomic flower-like FeCo magnetic nanoparticles are synthesized through a modified one-pot polyol technique. The as-prepared samples are annealed at 700 and 800 degrees C under reducing atmosphere. The saturation ...
    • 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 ...
