研究了倾斜磁场中半导体超晶格中电子磁畴随温度变化的时空动力学。结果表明，温度的升高实质上改变了系统的时空动力学。这导致流经半导体超晶格的电流的振荡频率和幅度降低。观察到了振荡的猝灭现象，这归因于漂移速度随温度变化而随电场强度的变化。
The space-time dynamics of electron domains in a semiconductor superlattice is studied in a tilted magnetic field with regard to the effect of temperature. It is shown that an increase in temperature substantially changes the space-time dynamics of the system. This leads to a decrease in the frequency and amplitude of oscillations of a current flowing through the semiconductor superlattice. The quenching of oscillations is observed, which is attributed to the change in the drift velocity as a function of electric-field strength under the variation of temperature.
