Current self-oscillations, spikes and crossover between charge monopole and dipole waves in semiconductor superlattices
David Sanchez, Miguel Moscoso, Luis L. Bonilla +2
Self-sustained current oscillations in weakly-coupled superlattices are studied by means of a self-consistent microscopic model of sequential tunneling including boundary condition…
Electrically tunable GHz oscillations in doped GaAs-AlAs superlattices
J. Kastrup, R. Hey, K. H. Ploog +5
Tunable oscillatory modes of electric-field domains in doped semiconductor superlattices are reported. The experimental investigations demonstrate the realization of tunable, GHz f…
Current-voltage characteristic and stability in resonant-tunneling n-doped semiconductor superlattices
A. Wacker, M. Moscoso, M. Kindelan +1
We review the occurrence of electric-field domains in doped superlattices within a discrete drift model. A complete analysis of the construction and stability of stationary field p…
Microscopic Model for Sequential Tunneling in Semiconductor Multiple Quantum Wells
Ramon Aguado, Gloria Platero, Miguel Moscoso +1
We propose a selfconsistent microscopic model of vertical sequential tunneling through a multi-quantum well.The model includes a detailed description of the contacts,uses the Trans…
Current-voltage characteristic, stability, and self-sustained current oscillations in resonant-tunneling n-doped semiconductor superlattices
L. L. Bonilla, M. Kindelan, M. Moscoso +1
We review the statics and dynamics of electric-field domains on doped superlattices within a discrete drift model. A complete analysis of the construction and stability of stationa…
