Stimulus pulse-dependent responses in natural DNA biopolymer devices

Abstract

In recent years, optoelectronic devices are implemented based on natural DNA with enhanced performance and efficiency. In this study, we present stimulus pulse-dependent responses in natural DNA biopolymer devices. The device consists of a simple sandwich structure and the resistivity can be manipulated with respect to voltage operation. We characterize the stimulus pulse-dependent responses, where the synaptic plasticity will be presented. To further explore dynamics of resistive states, the effect of incorporating a photo-responsive material on the light-triggered electrical characteristics will be discussed. Our results reveal natural DNA biopolymer shows great promise for the development of synaptic devices for neuromorphic circuitry.
