Anomaly of the current self-oscillation frequency in the sequential tunneling of a doped GaAsÕAlAs superlattice
An anomalous behavior of the current self-oscillation frequency is observed in the dynamic dc voltage bands, emerging from each sawtoothlike branch of the current-voltage characteristic of a doped GaAs/AlAs superlattice in the transition process from static to dynamic electric field domain formations. Varying the applied dc voltage at a fixed temperature, we find that the frequency increases wh...
متن کاملMagnetic field induced metastability in the self-doped manganites
We observe an interesting scenario of field induced metastabilities in the resistivity measurements. The resistivity exhibits a bifurcation of zero-field cooled and field-cooled (FC) temperature dependence below the paramagnetic to ferromagnetic transition (Tc). The clear evidence of inverse thermal hysteresis of resistivity is observed under FC condition in between 85 and 200 K, indicating the...
متن کاملSuperlattice properties of semiconductor nanohelices in a transverse electric field
A charge carrier confined in a quasi-one-dimensional semiconductor helical nanostructure in the presence of an electric field normal to the axis of the helix is subjected to a periodic potential proportional to the strength of the field and the helix radius. As a result, electronic properties of such nanohelices are similar to those of semiconductor superlattices with parameters controlled by t...
متن کاملDuffing oscillation-induced reversal of magnetic vortex core by a resonant perpendicular magnetic field
Nonlinear dynamics of the magnetic vortex state in a circular nanodisk was studied under a perpendicular alternating magnetic field that excites the radial modes of the magnetic resonance. Here, we show that as the oscillating frequency is swept down from a frequency higher than the eigenfrequency, the amplitude of the radial mode is almost doubled to the amplitude at the fixed resonance freque...
متن کاملSpontaneous DC Current Generation in a Resistively Shunted Semiconductor Superlattice Driven by a TeraHertz Field
We study a resistively shunted semiconductor superlattice subject to a highfrequency electric field. Using a balance equation approach that incorporates the influence of the electric circuit, we determine numerically a range of amplitude and frequency of the ac field for which a dc bias and current are generated spontaneously and show that this region is likely accessible to current experiments...
