Semiconductors can exhibit electrical instabilities like current runaway, threshold switching,
current filamentation, or oscillations, when they are driven far from thermodynamic …

Our life is a highly nonlinear process. It starts with birth and ends with death; in between
there are a lot of ups and downs. Quite often, we believe that stable and steady situations …

We are presenting an analytic model for the figures of merit of a novel extrinsic infrared
quantum detector—the blocked impurity band (BIB) detector. The detector consists of top …

Modern dynamical systems research, the study of the evolution in time of the solutions of
differential equations, has led to powerful observational tools for the experimentalist. In …

We present a novel approximation scheme, termed unified colored noise approximation
(UCNA), for colored Gaussian noise driven nonlinear systems with inertia. This …

Experimental results are reported for a driven, damped pendulum in which steady and/or
alteranting torques were applied by means of a modified brushless, slotless linear motor …

Cooled, extrinsic GE that is voltage biased to produce a spontaneous current oscillation
exhibits frequency locking, quasiperiodicity, and chaos when driven with a sinusoidal …

This paper reviews experimental and theoretical work carried out on space charge
instabilities and temporal chaotic behavior in cooled extrinsic p-type Germanium …

We consider the motion of ballistic electrons in a miniband of a semiconductor superlattice
(SSL) under the influence of an external, time-periodic electric field. We use a semiclassical …

Two-dimensional imaging of the nucleation and the dynamics of current filaments generated
in homogeneous p-doped germanium at 4.2 K during impurity impact ionization induced …
