2021年11月19日 · To demonstrate the electron correlation resulted magnetic property, we create a vertical 1T/2H NbSe 2 heterostructure, and we find unambiguous evidence of exchange interactions between the localized magnetic moments in 1T phase and the metallic/superconducting phase exemplified by Kondo resonances …

2016年11月4日 · We have synthesized a monolayer 1T-NbSe2 on bilayer graphene by molecular-beam-epitaxy method and investigated its electronic states by angle-resolved photoemission spectroscopy.

2024年3月15日 · Here we report on the experimental observation and theoretical modeling of QSL signatures in monolayer 1T-NbSe 2, which is a newly emerging two-dimensional material that exhibits both...

2015年7月20日 · Enhanced electron–phonon interactions in mono- and few-layer NbSe2 result in a significantly increased transition temperature of charge density waves compared with values in the bulk.

2018年7月23日 · We investigate the electronic structure of monolayer 1T-NbSe 2 by means of density-functional theory (DFT) with semilocal and hybrid functionals as well as many-body perturbation theory employing the GW approximation.

2024年1月16日 · Here, we demonstrate the realization of a doped Mott phase in a van der Waals dichalcogenide 1T-NbSe 2 monolayer. The system is electron doped due to electron transfer to a monolayer van der Waals substrate via proximity, leading to a correlated triangular lattice with both half-filled and fully-filled sites.

2021年3月24日 · Although 1T phase NbSe2 does not occur naturally in bulk form, it has been discovered that the 1T and 1H phases can coexist when monolayer NbSe2 is grown via molecular beam epitaxy (MBE). This discovery has inspired theoretical investigations predicting collective phenomena such as ferromagnetism in two dimensions.

新出现的 1T-NbSe 2激发了预测集体现象的理论研究，例如二维的电荷转移间隙和铁磁性；但是，仍然缺乏实验证据。 在这里，通过控制分子束外延生长参数，我们展示了高质量单相 1T-NbSe 2的成功生长.

2023年7月6日 · Correlated 2D layers, like 1T-phases of TaS 2, TaSe 2, and NbSe 2, exhibit rich tunability through varying interlayer couplings, which promotes the understanding of electron correlation in the 2D limit.

2021年8月5日 · Here, we study the charge transfer state in monolayer 1T-NbSe 2, an electronic analogue to TaS 2 exempt from interlayer coupling, using spectroscopic imaging scanning tunneling microscopy and first-principles calculations.
