By integrating colloidal quantum wells into the phototransistors, the researchers enabled the devices to operate with much higher sensitivity across a broad range of the visible spectrum, from blue to red light. The system\u2019s ability to be fabricated using low-cost and scalable production methods is significant for the development of more sensitive and adaptive devices for use in light sensors, smart displays, and a range of optoelectronic applications.<\/p>\n<p>Read Prof. Dr. Hilmi Volkan Demir\u2019s full article here: <a href=\"https:\/\/onlinelibrary.wiley.com\/doi\/10.1002\/lpor.202501814\">https:\/\/onlinelibrary.wiley.com\/doi\/10.1002\/lpor.202501814<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Bilkent University National Nanotechnology Research Center (UNAM) Director and Chair of the Materials Science and Nanotechnology Graduate Program Prof. Hilmi Volkan Demir and his research team recently published their work, [&hellip;]<\/p>\n","protected":false},"author":1,"featured_media":10892,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"inline_featured_image":false,"footnotes":""},"categories":[78],"tags":[],"class_list":["post-10896","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-2026-news"],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v19.13 - https:\/\/yoast.com\/wordpress\/plugins\/seo\/ -->\n<title>UNAM\u2019s Prof. Hilmi Volkan Demir\u2019s Research on Phototransistors with Enhanced Visible-Light Detection Published in Laser &amp;
