Seok Young Min and colleagues selectively converted parts of the top layer into tungsten oxide (WOx) as an insulator, and other regions into n-type WS2 and p-type WSe2. Combining these in-situ conversions produced functional MOSFETs without grafting on separate materials. The approach could allow atomic-scale device density higher than standard silicon semiconductor tech. Other researchers have explored similar transition-metal dichalcogenide monolayers, such as MoSe2, for the same purpose. ## Full article daily.dev links to this article rather than hosting it.

Seok Young Min and colleagues selectively transformed parts of a tungsten ditelluride (WTe2) monolayer into different functional regions in place. Part of the top layer became tungsten oxide (WOx), acting as an insulator, while other sections were converted into n-type WS2 and p-type WSe2, together forming a functional MOSFET without grafting on separate materials. _daily.dev surfaces research like this for engineers tracking what comes after silicon scaling limits._ ### What is the advantage of building transistors directly in a 2D material monolayer instead of using traditional silicon fabrication? Creating transistors in-situ within a transition-metal dichalcogenide (TMDC) monolayer, such as WTe2, avoids the multiple rounds of modifications and material grafting that silicon fabrication requires. Because the structures form at an atomic scale, this approach could potentially achieve device densities significantly higher than industry-standard silicon semiconductor technology allows. _follow emerging fabrication techniques like this on daily.dev before they reshape chip design decisions._ ## Similar posts on daily.dev - [Quantum-Tunnelling Field-Effect Transistor Designed to Overcome Integrated-Circuit Chip Development Barriers](https://daily.dev/posts/quantum-tunnelling-field-effect-transistor-designed-to-overcome-integrated-circuit-chip-development--1sphzuoo9) · The Quantum Insider · 0 upvotes · 0 comments - [Quantum phenomenon enables a nanoscale mirror that can be switched on and off](https://daily.dev/posts/quantum-phenomenon-enables-a-nanoscale-mirror-that-can-be-switched-on-and-off-1o195vebl) · Phys.org · 0 upvotes · 0 comments - [Researchers make air-stable, ultrathin superconductors, for more scalable quantum devices](https://daily.dev/posts/researchers-make-air-stable-ultrathin-superconductors-for-more-scalable-quantum-devices-ntid5a3xj) · MIT News · 0 upvotes · 0 comments - [Why Diamond Transistors Are So Hard To Make](https://daily.dev/posts/why-diamond-transistors-are-so-hard-to-make-uuzunh9p2) · Hackaday · 0 upvotes · 0 comments - [Singapore’s Nexstrom wants to bring 2D semiconductors to chip fabs](https://daily.dev/posts/singapore-s-nexstrom-wants-to-bring-2d-semiconductors-to-chip-fabs-sj91buskh) · TechCrunch · 0 upvotes · 0 comments --- Tags: [#science](https://daily.dev/tags/science) [View this post on daily.dev](https://daily.dev/posts/transforming-a-tungsten-ditelluride-monolayer-into-a-transistor-ykumljhdd) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@type":"TechArticle","headline":"Transforming A Tungsten Ditelluride Monolayer Into A Transistor","url":"https://daily.dev/posts/transforming-a-tungsten-ditelluride-monolayer-into-a-transistor-ykumljhdd","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/transforming-a-tungsten-ditelluride-monolayer-into-a-transistor-ykumljhdd"},"datePublished":"2026-10-26T02:33:14.569Z","dateModified":"2026-10-26T02:44:10.501Z","description":"Researchers created a working transistor directly within a single tungsten ditelluride (WTe2) monolayer.
