Janus 2D materials have drawn substantial attention recently owing to its extraordinary interface properties and promising applications in optoelectronic devices. However, the scalable fabrication of high-quality Janus 2D materials is still one of the main obstacles to hinder its implementation in the industry. Herein, a new method (called “chemical breakdown”) is developed to obtain large-area uniform Janus graphene oxide (J-GO) films with high-quality. Moreover, the first application of J-GO in the field of memristive devices is presented for neuromorphic computing. In particular, crossbar arrays of Ag/J-GO/Au memristive devices that exhibit threshold resistive switching (RS) with enhanced performance are fabricated, e.g., low leakage current (≈10−12 A), low operation voltage (≈0.3 V), high endurance (>12,000 cycles), and electro-synaptic plasticity. This work provides a novel strategy to obtain large-area, continuous and uniform Janus 2D films, and proposes a new application for Janus 2D materials in a hot topic (i.e., neuromorphic computing) within the field of solid-state microelectronics.
