However, the existing ferroelectric diodes based on ferroelectric oxides suffer from a weak bidirectional photoresponse (below 1 mA/W), difficult miniaturization, and a large response photon energy (over 3 eV). Here, we design a series of van der Waals&amp;nbsp;�−In2Se3/Nb�2&amp;nbsp;(�&amp;nbsp;= S, Se, and Te) ferroelectric diodes with bidirectional photoresponse by using&amp;nbsp;&lt;em&gt;ab initio&lt;/em&gt;&amp;nbsp;quantum transport simulation. These devices show a maximum bidirectional photoresponse of 30 (−19) mA/W and a minimum response photon energy of 1.3 eV at the monolayer thickness. Our work shows advanced optoelectronic applications of the van der Waals ferroelectric diodes in the future artificial neuromorphic system.</style></abstract></record></records></xml>
