Recent advances in superlattice frequency multipliers
Yuliia Shevchenko, Apostolos Apostolakis, Mauro F. Pereira
Semiconductor superlattice multipliers have emerged as a nonlinear medium capable to generate radiation in a wide frequency range. This property facilitates the potential of source…
Superlattice nonlinearities for Gigahertz-Terahertz generation in harmonic multipliers
Apostolos Apostolakis, Mauro F. Pereira
Semiconductor superlattices are strongly nonlinear media offering several technological challenges associated with the generation of high-frequency Gigahertz radiation and very eff…
Potential and limits of superlattice multipliers coupled to different input power sources
A. Apostolakis, M. F. Pereira
A theoretical study is presented to assess the performance of semiconductor superlattice multipliers as a function of the currently available input power sources. The prime devices…
Controlling the harmonic conversion efficiency in semiconductor superlattices by interface roughness design
Apostolos Apostolakis, Mauro F. Pereira
In semiconductor superlattices, when Bragg oscillating electrons interact with an input electromagnetic field, frequency multiplication is possible. An ideal superlattice has a pur…
Simple electron-electron scattering in non-equilibrium Green's function simulations
David O. Winge, Martin Franckié, Claudio Verdozzi +2
In this work we include electron-electron interaction beyond Hartree-Fock level in our non-equilibrium Green's function approach by a crude form of GW through the Single Plasmon Po…
