Periodically generated propagating pulses
L. L. Bonilla, M. Kindelan, J. B. Keller
Certain equations with integral constraints have as solutions time-periodic pulses of a field-like unknown while a current-like unknown oscillates periodically with time. A general…

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…
