The team focused on the properties of \u201ctwisted bilayer graphene,\u201d a structure formed by stacking two layers of graphene at a specific \u201cmagic angle\u201d (approximately 1.1 degrees), first observed in 2018 to exhibit superconductivity. However, the latest findings further unveil that electrons within this structure can organize themselves into a perfectly ordered array and rotate in sync, akin to ballet dancers spinning in place. This results in the material\u2019s interior remaining insulating, while its edges conduct current without resistance.<\/p>\n\n\n\n<p class=\"has-medium-font-size\">UBC undergraduate Ruiheng Su made the initial observation while studying twisted bilayer graphene samples produced by University of Washington postdoctoral researcher Dacen Waters. Experiments demonstrated that the magnitude of the edge current is determined by the ratio of Planck\u2019s constant to the electron charge. This quantum behavior is protected by topological properties, rendering it impervious to environmental disturbances.<\/p>\n\n\n\n<h2 class=\"wp-block-heading has-ast-global-color-0-color has-text-color has-link-color wp-elements-65c48b6893aea88d4d4f9df184663532\" id=\"\u83ab\u723e\u689d\u7d0b\u8207\u96fb\u5b50\u904b\u52d5\u7684\u8f49\u8b8a\">The Transformation of Electron Motion Through the Moir\u00e9 Pattern<\/h2>\n\n\n\n<p class=\"has-medium-font-size\">The \u201cmoir\u00e9 pattern\u201d effect is crucial to this research. When two layers of graphene are stacked at a slight angle, a unique geometric interference pattern emerges. In certain areas, carbon atoms align directly, while in others, they are slightly misaligned. This arrangement significantly influences electron behavior.<\/p>\n\n\n\n<p class=\"has-medium-font-size\">UBC physicist Joshua Folk explains: \u201cWhen electrons move in this twisted graphene structure, their velocity slows down considerably. Sometimes, they develop a twisting motion, like whirlpools forming as water flows past a drain.\u201d This phenomenon alters the dynamics of electrons within the graphene, prompting them to form crystalline arrays internally while allowing edge currents to flow steadily.<\/p>\n\n\n\n<h2 class=\"wp-block-heading has-ast-global-color-0-color has-text-color has-link-color wp-elements-4baa37c4c6ba4fcd5663be4e844ab578\" id=\"\u83ab\u6bd4\u70cf\u65af\u5e36\u8207\u62d3\u64b2\u96fb\u5b50\u6676\u9ad4\u7684\u806f\u7e6b\">The Link Between the M\u00f6bius Strip and the Topological Electronic Crystal<\/h2>\n\n\n\n<p class=\"has-medium-font-size\">The researchers drew an analogy between this peculiar electronic state and the M\u00f6bius strip, a topological structure with only one surface. Even when deformed, the M\u00f6bius strip retains its unique mathematical properties. Similarly, the edge currents in this topological electronic crystal maintain stable flow, even amidst environmental interference.<\/p>\n\n\n\n<p class=\"has-medium-font-size\">University of Washington professor Matthew Yankowitz states: \u201cWhat\u2019s strange about this electronic state is that even though the interior electrons are frozen into a stable array, the edges are still conductive. This is a property not previously seen in traditional Wigner crystals.\u201d<\/p>\n\n\n\n<p class=\"has-medium-font-size\">The topological nature of this discovery suggests that electron behavior is governed by the overall structure, not by local noise or material defects. This can provide a stable electronic state foundation for future quantum computing.<\/p>\n\n\n\n<h2 class=\"wp-block-heading has-ast-global-color-0-color has-text-color has-link-color wp-elements-2cb4a658fda170a8d1d32c90666a1b00\" id=\"\u7d50\u8ad6\">Conclusion<\/h2>\n\n\n\n<p class=\"has-medium-font-size\">The implications of this research extend beyond theoretical physics, potentially impacting quantum information technology, advanced materials science, and energy storage. Researchers are currently exploring how to combine this topological electronic crystal with superconductivity to develop novel topological qubits, laying the groundwork for the next generation of quantum computers. Furthermore, the property of being insulating internally but conductive at the edges could lead to the creation of new types of electronic components, sparking technological innovations in electrical engineering and renewable energy.<\/p>\n\n\n\n<p class=\"has-medium-font-size\">The potential of graphene continues to be unveiled, and this discovery marks a new stage in scientists\u2019 understanding of quantum physics, paving the way for the development of future quantum computing technologies and high-performance materials.<\/p>\n\n\n\n<p>References:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Twisted Bilayer Graphene Exhibits Unique Quantum State: Insulating Bulk, Conductive Boundary<\/li>\n\n\n\n<li>Electrons Frozen Yet Free: A Quantum Breakthrough in Graphene<\/li>\n\n\n\n<li>Ruiheng Su, Dacen Waters, Boran Zhou, Kenji Watanabe, Takashi Taniguchi, Ya-Hui Zhang, Matthew Yankowitz, Joshua Folk (2025). <em>Moir\u00e9-driven topological electronic crystals in twisted graphene<\/em>, <em>Nature<\/em>, 637, 1084\u20131089. <a href=\"https:\/\/www.nature.com\/articles\/s41586-024-08239-6\" data-type=\"link\" data-id=\"https:\/\/www.nature.com\/articles\/s41586-024-08239-6\" rel=\"nofollow noopener\" target=\"_blank\">DOI: 10.1038\/s41586-024-08239-6.<\/a><\/li>\n<\/ul>\n\n\n\n<p>Source of the first image: AI generated<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity is-style-wide\"\/>\n\n\n\n<p>We offer customized adjustments to the grinding process, tailored to meet processing requirements for maximum efficiency.<\/p>\n\n\n\n<p style=\"line-height:0.8\">Feel free to contact us and we will have specialist available to answer your questions.<\/p>\n\n\n\n<p style=\"line-height:0.8\">If you need customized quotations, you\u2019re also welcome to contact us.<\/p>\n\n\n\n<p style=\"line-height:0.8\">Customer Service Hours: Monday to Friday 09:00~18:00 (GMT+8)<\/p>\n\n\n\n<p style=\"line-height:0.8\">Phone: +886<a href=\"https:\/\/www.google.com\/search?q=%E5%AE%8F%E5%B4%B4&amp;oq=%E5%AE%8F%E5%B4%B4&amp;gs_lcrp=EgZjaHJvbWUqBggAEEUYOzIGCAAQRRg7MhAIARAuGK8BGMcBGIAEGI4FMgYIAhBFGDsyBwgDEAAYgAQyBggEEEUYPTIGCAUQRRg9MgYIBhBFGD0yBggHEEUYQdIBCDE5MDhqMGo3qAIIsAIB&amp;sourceid=chrome&amp;ie=UTF-8\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">7 223 1058<\/a><\/p>\n\n\n\n<p style=\"line-height:0.8\">If you have a subject that you want to know or a phone call that is not clear, you are welcome to send a private message to Facebook~~<\/p>\n\n\n\n<p style=\"line-height:0.8\">Honway Facebook: <a href=\"https:\/\/lihi.cc\/LhR8c\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">https:\/\/www.facebook.com\/honwaygroup<\/a><\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<div class=\"wp-block-buttons is-layout-flex wp-block-buttons-is-layout-flex\">\n<div class=\"wp-block-button\"><a class=\"wp-block-button__link has-ast-global-color-0-background-color has-background wp-element-button\" href=\"https:\/\/honwaygroup.com\/en\/honway-raw-materials\/\" target=\"_blank\" rel=\"noreferrer noopener\">We are Honway, by controlling our raw materials from the source, we ensure the quality of our products and offer you customized options.<\/a><\/div>\n<\/div>\n\n\n\n<ul class=\"wp-block-jetpack-sharing-buttons has-normal-icon-size jetpack-sharing-buttons__services-list\" id=\"jetpack-sharing-serivces-list\">\n\n\n\n<\/ul>\n\n\n\n<div style=\"height:100px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<p>You may be interested in&#8230;<\/p>\n\n\n\n<div class=\"wp-block-columns is-layout-flex wp-container-core-columns-is-layout-28f84493 wp-block-columns-is-layout-flex\">\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\" style=\"flex-basis:100%\"><p>[wpb-random-posts]<\/p>\n<\/div>\n<\/div>\n\n\n\n<p><\/p>\n","protected":false},"excerpt":{"rendered":"<p>In recent years, graphene has garnered widespread attention in materials science and quantum computing due to its exceptional conductivity, strength, and unique quantum properties.
