Photo-Detectors Integrated with Resonant Tunneling Diodes

We report on photo-detectors consisting of an optical waveguide that incorporates a resonant tunneling diode (RTD). Operating at wavelengths around 1.55 μm in the optical communications C band we achieve maximum sensitivities of around 0.29 A/W which is dependent on the bias voltage. This is due to the nature of RTD nonlinear current-voltage characteristic that has a negative differential resis...

Controlling chaotic systems with multiple strange attractors

It is shown how chaotic systems with more than one strange attractor can be controlled. Issues in controlling multiple (coexisting) strange attractors are stabilizing a desired motion within one attractor as well as taking the system dynamics from one attractor to another. Realization of these control objectives is demonstrated using a numerical example, the Newton–Leipnik system.  2002 Elsevi...

Simulation of Resonant Tunneling Diodes Using ATLAS

This article describes a model for Resonant Tunneling Diodes (RTDs) implemented within ATLAS framework. The model is based on a self-consistent solution of Poisson and Non-Equilibrium Green’s Function (NEGF) equations with an effective mass Hamiltonian. Simulation results are presented for generic GaAs and SiGe RTDs.
