## Description

- description: We demonstrate a two-terminal optoelectronic synaptic device based
    on the poly-crystal diamond to incorporate persistent photoconductive (PPC) behavior
    into optoelectronic synapse. The inherent photosensitive memory nature is derived
    from the PPC effect induced by defects including grain boundary, color center,
    C vacancy, and non-diamond phase, which successfully mimics the dynamics of biological
    synapses. More importantly, the intentionally introduced N related deep levels
    contribute to the longevity of the photo-excited carriers, offering a nonvolatile
    photo-switch in a diamond device. The diamond synapse realizes a maximum paired
    pulse facilitation (PPF) index of 174 % and effectively imitate the learning-forgetting-relearning
    behavior of human brain. Moreover, an encryption strategy is proposed inspired
    by the synaptic device, offering a new way to improve the security in optical
    communication.
