Noise influence on characteristics of current, flowing through semiconductor superlattice, in high frequency oscillation mode

Noise influence on characteristics of current, flowing through semiconductor superlattice of nanodevice with prospects of using in terahertz spectroscopy, is examined. It is demonstrated, that the limit voltage, at which the current oscillations start, slightly depends on noise intensity. Oscillation amplitude increases at some noise intensity values for case without magnetic field and in the presence of a tilted magnetic field. At the same time with increase of noise intensity at developed oscillations the basic frequency decreases, while higher harmonics amplitudes can significantly decrease.
