Author(s): Zhengzheng Shao, Zhizhen Yin, Helun Song, Wei Liu, Xiujian Li, Jubo Zhu, Klaus Biermann, Luis L. Bonilla, Holger T. Grahn, and Yaohui Zhang The effect of a coherence resonance is observed experimentally in a GaAs / Al 0.45 Ga 0.55 As superlattice under dc bias at room temperature, which is driven by noise. For an applied voltage, for which no current self-oscillations are observed, regular current self-oscillations with a frequency of about 8... [Phys. Rev. Lett. 121, 086806] Published Fri Aug 24, 2018
