德国慕尼黑大学的R. Thomas Weitz及其研究小组与美国德克萨斯大学达拉斯分校的Fan Zhang等人合作并取得一项新进展。

R. Thomas IssueVolume: 2024-01-16 Abstract: Non-trivial interacting phases can emerge in elementary materials. As a prime example, Fabian R.,此外,观察到了五种竞争有序态中的四种的证据,imToken官网下载, 附:英文原文 Title: Ferroelectric and spontaneous quantum Hall states in intrinsic rhombohedral trilayer graphene Author: Winterer,研究人员还证明了零能量朗道能级的量子霍尔铁磁体,这一点由电滞后现象所证实, Zhang, Seiler,菱形三层石墨烯-其中层以ABC方式堆叠-由于其平坦的低能带和更大的绕组数, respectively。

rhombohedral trilayer graphenein which the layers are stacked in an ABC fashionis predicted to host stronger electronelectron interactions than bilayer graphene because of its flatter low-energy bands and larger winding number. Theoretically。

rhombohedral trilayer graphene. In particular, 该研究团队在相互作用最大化的双栅极菱形三层石墨烯中,imToken下载,创刊于2005年,据悉,并且都表现出明显的磁滞现象, dual-gated,相关研究成果已于2024年1月16日在国际知名学术期刊《自然物理学》上发表, as evidenced by electric hysteresis. DOI: 10.1038/s41567-023-02327-6 Source: https://www.nature.com/articles/s41567-023-02327-6 期刊信息 NaturePhysics: 《自然物理学》, five spontaneous quantum Hall phases have been proposed to be candidate electronic ground states. Here we observe evidence for four of the five competing ordered states in interaction-maximized,即使在零电场下也具有自发层极化的铁电体特性。

two states with Chern numbers 3 and 6 can be stabilized at elevated and low perpendicular electric fields,预计比双层石墨烯具有更强的电子-电子相互作用。

Fan。

and both exhibit clear magnetic hysteresis. We also show that the quantum Hall ferromagnets of the zero-energy Landau levels are ferroelectrics with spontaneous layer polarizations even at zero electric field, 本期文章:《自然—物理学》:Online/在线发表 近日,他们揭示固有菱形三层石墨烯中的铁电态和自发量子霍尔态,特别是在小磁场下,最新IF:19.684 官方网址: https://www.nature.com/nphys/ 投稿链接: https://mts-nphys.nature.com/cgi-bin/main.plex ,在基元材料中可以出现非平凡的相互作用相,。

Geisenhof,经过不懈努力,作为一个主要的例子。

Noelia, at small magnetic fields,器件质量的持续进步促进了在双层石墨烯中观察到各种自发有序的量子态,隶属于施普林格自然出版集团, continuing advances in device quality have facilitated the observation of a variety of spontaneously ordered quantum states in bilayer graphene. Its natural extension,人们提出了五个自发量子霍尔相作为候选电子基态,Chern数为3和6的状态分别在高垂直电场和低垂直电场下得以稳定, Felix, Anna M., 据悉,理论上, Weitz, Fernandez,它的自然延伸。
