摘要

摘要研究了噪声对流经半导体超晶格纳米器件的电流特性的影响，该器件有望用于太赫兹光谱分析。研究表明，电流振荡开始的极限电压略微取决于噪声强度。在无磁场和有倾斜磁场的情况下，当噪声强度达到一定值时，振荡幅度会增大。同时，随着噪声强度的增加，产生振荡时的基本频率会降低，而高次谐波振幅会显著减小。

Noise Influence on Characteristics of Current, Flowing through Semiconductor Superlattice, in High Frequency Oscillation Mode

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.
