Researchers from Harvard University and the University of California, Berkeley have developed MEGA2D, a micro-electromechanical system that allows for the precise twisting of ultra-thin materials. This innovation could lead to transformative advancements in technology ranging from high-performance transistors to quantum computers.<\/p>\n\n\n\n<p>In a landmark 2018 paper, researchers revealed that graphene layers, when slightly twisted, could act as superconductors. This opened the door to &#8220;twistronics,&#8221; a subfield that manipulates the electronic properties of materials through controlled twisting. However, the process was laborious and time-consuming, often requiring the creation of hundreds of unique samples.<\/p>\n\n\n\n<p>Yuan Cao, formerly an MIT graduate student and a leading figure in the initial twistronics discovery, collaborated with Harvard physicists Amir Yacoby and Eric Mazur to address this challenge. Their new device, <a href=\"https:\/\/www.nature.com\/articles\/s41586-024-07826-x\" title=\"\">described<\/a> in the latest issue of Nature, simplifies the twisting process, enabling real-time manipulation and study of various materials.<\/p>\n\n\n\n<p>&#8220;This development makes twisting as easy as controlling the electron density of 2D materials,&#8221; Yacoby, a Harvard professor of physics and applied physics, said in a <a href=\"https:\/\/news.harvard.edu\/gazette\/story\/2024\/09\/a-smoother-way-to-study-twistronics\/\" title=\"\">news release<\/a>. &#8220;Controlling density has been the primary knob for discovering new phases of matter in low-dimensional matter, and now, we can control both density and twist angle, opening endless possibilities for discovery.\u201d<\/p>\n\n\n\n<p><\/p>\n\n\n\n<p>The MEGA2D device, no larger than a fingernail, offers a versatile platform for exploring the potentials of materials like hexagonal boron nitride and graphene. The researchers have already demonstrated its efficacy by studying the optical properties of a bilayer hexagonal boron nitride device, uncovering quasiparticles with topological properties.<\/p>\n\n\n\n<p>&#8220;By having this new \u2018knob\u2019 via our MEGA2D technology, we envision that many underlying puzzles in twisted graphene and other materials could be resolved in a breeze,&#8221; Cao, currently an assistant professor at UC Berkeley, said in the news release. &#8220;It will certainly also bring other new discoveries along the way.&#8221;<\/p>\n\n\n\n<p>The first author of the pioneering paper, Haoning Tang, a postdoctoral researcher in Mazur&#8217;s lab, emphasized the arduous journey to this breakthrough. <\/p>\n\n\n\n<p>&#8220;We didn\u2019t know much about how to control the interfaces of 2D materials in real time, and the existing methods just weren\u2019t cutting it,&#8221; she added. &#8220;After spending countless hours in the cleanroom and refining the MEMS design \u2014 despite many failed attempts \u2014 we finally found the working solution after about a year of experiments.&#8221;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>A groundbreaking discovery in the field of condensed-matter physics has ushered the phenomenon known as &#8220;twistronics&#8221; into a new era.
