    Terahertz and infrared photodetectors based on multiple graphene layer and nanoribbon structures

    We consider new concepts of terahertz and infrared photodetectors based on multiple graphene layer and multiple graphene nanoribbon structures and we evaluate their responsivity and detectivity. The performanc...

    Terahertz laser based on optically pumped graphene: Model and feasibility of realization

    We consider a terahertz laser based on optically pumped graphene layer and bilayer as the active media and suggested waveguide structure. Using the developed model, we calculate the spectral dependences the dy...

    Effect of the Coulomb scattering on graphene conductivity

    The effect of the Coulomb scattering on graphene conductivity in field-effect transistor structures is discussed. Interparticle scattering (electron-electron, hole-hole, and electron-hole) and scattering on ch...

    Absolute negative conductivity and zero-resistance states in two-dimensional electron systems: A plausible scenario

    We present a model that provides a plausible explanation of the effect of zero-resistance and zero-conductance states in two-dimensional electron systems subjected to a magnetic field and irradiated with micro...
