However, most existing implementations require precise control over the excitation wavelength, optical power, or gate bias, which complicates device fabrication and system integration. Here, we demonstrate a reconfigurable optoelectronic logic device based on a VSe2\/MoTe2 van der Waals heterojunction. The device exhibits a rectification ratio exceeding 103 in the dark and a pronounced photovoltaic response, including a light on\/off ratio surpassing 107, a responsivity of 0.28 A\/W, and external quantum efficiency of 54%, as well as a noise-equivalent power of 4.6 \u00d7 10\u221214 W\/Hz1\/2 and a specific detectivity of 2.1 \u00d7 1010 cm Hz1\/2\/W. By reconfiguring the source and drain electrodes and modulating the optical input, six fundamental Boolean logic operations\u2014AND, IMP, NOR, NOT, OR, and NAND\u2014are realized in the device. Notably, all six logic functions are obtained under fixed illumination and predefined bias, without requiring wavelength, power, or gate modulation. Switching between functions requires only a specific bias voltage and a change in the source\/drain connection (for certain operations, OR and NAND, the input state is redefined). These results underscore the promise of two-dimensional material-based van der Waals heterojunctions for compact, low-power, and reconfigurable optoelectronic logic processing.<\/jats:p>","DOI":"10.3390\/nano16191247","type":"journal-article","created":{"date-parts":[[2026,10,2]],"date-time":"2026-10-02T08:15:18Z","timestamp":1790928918000},"page":"1247","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Reconfigurable Optoelectronic Logic Gates Enabled by a VSe2\/MoTe2 van der Waals Heterojunction"],"prefix":"10.3390","volume":"16","author":[{"given":"Kang","family":"Zhang","sequence":"first","affiliation":[{"name":"State Key Laboratory of Opto-Electronic Information Acquisition and Protection Technology, Institutes of Physical Science and Information Technology, Anhui University, Hefei 230601, China"}],"role":[{"vocabulary":"crossref","role":"author"},{"role":"data-curation","vocabulary":"credit"},{"role":"investigation","vocabulary":"credit"},{"role":"methodology","vocabulary":"credit"}]},{"given":"Wansong","family":"He","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Opto-Electronic Information Acquisition and Protection Technology, Institutes of Physical Science and Information Technology, Anhui University, Hefei 230601, China"}],"role":[{"vocabulary":"crossref","role":"author"},{"role":"investigation","vocabulary":"credit"},{"role":"methodology","vocabulary":"credit"}]},{"given":"Ruya","family":"Cong","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Opto-Electronic Information Acquisition and Protection Technology, Institutes of Physical Science and Information Technology, Anhui University, Hefei 230601, China"}],"role":[{"vocabulary":"crossref","role":"author"},{"role":"investigation","vocabulary":"credit"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7166-036X","authenticated-orcid":false,"given":"Xin","family":"Zhang","sequence":"additional","affiliation":[{"name":"School of Physics and Information Technology, Shaanxi Normal University, Xi\u2019an 710119, China"}],"role":[{"vocabulary":"crossref","role":"author"},{"role":"supervision","vocabulary":"credit"},{"role":"funding-acquisition","vocabulary":"credit"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7636-8221","authenticated-orcid":false,"given":"Jianzhi","family":"Gao","sequence":"additional","affiliation":[{"name":"School of Physics and Information Technology, Shaanxi Normal University, Xi\u2019an 710119, China"}],"role":[{"vocabulary":"crossref","role":"author"},{"role":"supervision","vocabulary":"credit"},{"role":"funding-acquisition","vocabulary":"credit"}]},{"given":"Yubing","family":"Tu","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Opto-Electronic Information Acquisition and Protection Technology, Institutes of Physical Science and Information Technology, Anhui University, Hefei 230601, China"},{"name":"Key Laboratory of Opto-Electronic Information Acquisition and Manipulation of Ministry of Education, Anhui University, Hefei 230601, China"}],"role":[{"vocabulary":"crossref","role":"author"},{"role":"project-administration","vocabulary":"credit"},{"role":"writing-original-draft","vocabulary":"credit"},{"role":"supervision","vocabulary":"credit"},{"role":"formal-analysis","vocabulary":"credit"}]},{"given":"Suofu","family":"Wang","sequence":"additional","affiliation":[{"name":"School of Energy, Power and Safety, Anhui University of Applied Technology, Hefei 230011, China"}],"role":[{"vocabulary":"crossref","role":"author"},{"role":"project-administration","vocabulary":"credit"},{"role":"writing-review-editing","vocabulary":"credit"},{"role":"formal-analysis","vocabulary":"credit"}]},{"given":"Mingsheng","family":"Long","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Opto-Electronic Information Acquisition and Protection Technology, Institutes of Physical Science and Information Technology, Anhui University, Hefei 230601, China"},{"name":"Key Laboratory of Opto-Electronic Information Acquisition and Manipulation of Ministry of Education, Anhui University, Hefei 230601, China"}],"role":[{"vocabulary":"crossref","role":"author"},{"role":"funding-acquisition","vocabulary":"credit"},{"role":"supervision","vocabulary":"credit"}]}],"member":"1968","published-online":{"date-parts":[[2026,10,2]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"699","DOI":"10.1038\/nnano.2012.193","article-title":"Electronics and Optoelectronics of Two-Dimensional Transition Metal Dichalcogenides","volume":"7","author":"Wang","year":"2012","journal-title":"Nat.
