摘要: For widespectrum chaotic oscillation, superlattice cryptography is an autonomous controllable brand-new technology. Originating from sequential resonance tunneling of electrons, the chaotic oscillation is susceptible to temperature change, which determines the performance of superlattices. In this paper, the temperature effects of chaotic oscillations are investigated by analyzing the randomness of a sequence at different temperatures and explained with superlattice microstates. The results show that the bias voltage at different temperatures makes spontaneous chaotic oscillations vary. With the temperature of superlattices changing, the sequence dives in entropy value and randomness at specific bias. This work fills the gap in the study of temperature stability and promotes superlattice cryptography for practice.
