2D BDiode – A switchable bidirectional diode for analog electronic circuits fabricated entirely from 2D materials

The advent of two-dimensional (2D) materials has led to innovative and compact electronic devices with remarkable properties. In this work, we introduce a switchable bidirectional diode (2D BDiode), fabricated entirely using different 2D materials, that serves as a fundamental building block for various analog circuit applications. This proof-of-concept diode exhibits the ability to control the flow of current in both forward and reverse bias configurations, enabling advanced functionality in the realm of analog circuit design. We provide a SPICE-based model for the diode based on current-voltage device characterization, capturing its behavior under different biasing conditions, and finally demonstrate a few potential use cases of the 2D BDiode including AC/DC conversion, DC/AC conversion and charge pump circuits. • Fully 2D material device. • Bidirectional diode switchable by back-gate. • SPICE model implemented. • Analog electronic applications proposed and simulated including advanced AC/DC converter, DC/AC converter and charge pump.
