Abstract

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.

高频振荡模式下噪声对流经半导体超晶格的电流特性的影响

摘要

研究了噪声对流经纳米器件半导体超晶格的电流特性的影响，并具有在太赫兹光谱中的应用前景。结果表明，电流振荡开始的极限电压稍微依赖于噪声强度。对于没有磁场和存在倾斜磁场的情况，振荡幅度在某些噪声强度值处增加。同时，随着振荡中噪声强度的增加，基本频率会降低，而高次谐波幅度会显着降低。
