Dynamics of optically injected currents in carbon nanotubes
L. L. Bonilla, M. Alvaro, M. Carretero +1
We consider theoretically the dynamics of electric currents optically injected in carbon nanotubes. Although the plasma oscillations are not seen in these systems, the main effect…
Noise enhanced spontaneous chaos in semiconductor superlattices at room temperature
M. Alvaro, M. Carretero, L. L. Bonilla
Physical systems exhibiting fast spontaneous chaotic oscillations are used to generate high-quality true random sequences in random number generators. The concept of using fast pra…
Numerical method for hydrodynamic modulation equations describing Bloch oscillations in semiconductor superlattices
M. Álvaro, M. Carretero, L. L. Bonilla
We present a finite difference method to solve a new type of nonlocal hydrodynamic equations that arise in the theory of spatially inhomogeneous Bloch oscillations in semiconductor…
Theory of spatially inhomogneous Bloch oscillations in semiconductor superlattices
L. L. Bonilla, M. Álvaro, M. Carretero
In a semiconductor superlattice with long scattering times, damping of Bloch oscillations due to scattering is so small that nonlinearities may compensate it and Bloch oscillations…
Spatially confined Bloch oscillations in semiconductor superlattices
L. L. Bonilla, M. Álvaro, M. Carretero
In a semiconductor superlattice with long scattering times, damping of Bloch oscillations due to scattering is so small that convective nonlinearities may compensate it and Bloch o…
Nonequilibrium free energy, H theorem and self-sustained oscillations for Boltzmann-BGK descriptions of semiconductor superlattices
M Alvaro, L L Bonilla
Semiconductor superlattices (SL) may be described by a Boltzmann-Poisson kinetic equation with a Bhatnagar-Gross-Krook (BGK) collision term which preserves charge, but not momentum…
Two mini-band model for self-sustained oscillations of the current through resonant tunneling semiconductor superlattices
M. Alvaro, L. L. Bonilla
A two miniband model for electron transport in semiconductor superlattices that includes scattering and interminiband tunnelling is proposed. The model is formulated in terms of Wi…
Nonlinear electron and spin transport in semiconductor superlattices
L. L. Bonilla, L. Barletti, M. Alvaro
Nonlinear charge transport in strongly coupled semiconductor superlattices is described by Wigner-Poisson kinetic equations involving one or two minibands. Electron-electron collis…
