Superlattices in chaotic state can be used as a key part of a true random number generator.The chaotic characteristics of the signal generated in the superlattice are mostly affected by the parameters of the supedattice and the applied voltage,while the latter is easier to adjust.In this paper,the model of the superlattice is first established.Then,based on this model,the chaotic characteristics of the generated signal are studied under different voltages.The results demonstrate that the onset of chaos in the supedattice is typically accompanied by the mergence of multistability,and there are voltage intervals in each of which the generated signal is chaotic.
