  • Bandgap engineering in aperiodic Thue-Morse graphene superlattices 
    Carrillo Delgado, Enrique Arturo; Gaggero Sager, Luis Manuel; Rodríguez Vargas, Isaac (American Institute of Physics, 2019-01-25)
    The lack of bandgap in graphene is the main factor that prevents that this outstanding material be implemented in optoelectronics. In this work, we show that by nanostructuring graphene aperiodically it is possible to have ...
  • Controlling the optical absorption properties of d-FETs by means of contact voltage and hydrostatic pressure effects 
    Oubram, Outmane; Navarro, Oracio; Rodríguez-Vargas, Isaac; Gaggero-Sager, Luis Manuel; Noverolas, Humberto G. (Elsevier, 2019-03-15)
    The effects of contact voltage and hydrostatic pressure on subband structure and optical transitions in GaAs delta-Field Effect Transistor (δ-FET) are theoretically studied. The electronic structure of δ-FET under hydrostatic ...
  • Enhancement of Fano-resonance response in bilayer graphene single and double barriers induced by bandgap opening 
    Briones Torres, José Alberto; Pérez Álvarez, Rolando; Pernas Salomón, René; Rodríguez Vargas, Isaac (Elsevier, 2020-05-10)
    Fano resonances in bilayer graphene arise due to the coupling between extended and discrete electrons states, and represent an exotic phenomenon in graphene akin to Klein and anti-Klein tunneling, atomic collapse and ...
  • Non-conventional graphene superlattices as electron band-pass filters 
    Sánchez-Arellano, Arsenio; Madrigal Melchor, Jesús; Rodríguez Vargas, Isaac (Springer Nature, 2019-06-19)
    Electron transmission through different non-conventional (non-uniform barrier height) gated and gapped graphene superlattices (GSLs) is studied. Linear, Gaussian, Lorentzian and Pöschl-Teller superlattice potential profiles ...
  • Pseudospin-dependent Zitterbewegung in monolayer graphene 
    Serna, Eduardo; Rodríguez Vargas, Isaac; Pérez Álvarez, Rolando; Diago Cisneros, Leovildo (American Institute of Physics, 2019-05-23)
    We propose a spintronic device based on a narrow nanoribbon patterned from a monolayer graphene (MLG) sheet, embedded between a film of hexagonal boron nitride and a SiO2 substrate, all comprised under a three top-gated ...
  • TM plasmonic modes in a multilayer graphene-dielectric structure 
    Madrigal Melchor, Jesus; Perez Huerta, Jose Samuel; Suarez Lopez, Jaime Raul; Rodriguez Vargas, Isaac; Ariza Flores, David (Elsevier, 2019-01-10)
    Optical and electronic properties of multilayer systems have been extensively studied in the last years due to its potential applications in high-performance optoelectronic and photonic devices. In particular, the role of ...
