2015年11月9日 · In this work, we demonstrate very high in-plane upper critical fields induced by spin–momentum locking in superconducting monolayers of group-V TMD niobium diselenide (NbSe 2). This was...

2017年8月30日 · Atomic-resolution scanning transmission electron microscope imaging reveals the atomic structure of the intrinsic point defects and grain boundaries in monolayer NbSe 2, and confirms the low...

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.

2021年11月19日 · Monolayer group V transition metal dichalcogenides in their 1T phase have recently emerged as a platform to investigate rich phases of matter, such as spin liquid and ferromagnetism, resulting from strong electron correlations.

2020年10月5日 · Recent studies on superconductivity in NbSe 2 have demonstrated a large anisotropy in the superconducting critical field when the material is reduced to a single monolayer. Motivated by this recent discovery, we use density-functional theory (DFT) calculations to quantitatively address the superconducting properties of bulk and monolayer NbSe 2.

2025年1月15日 · Here, using heat capacity measurements we unambiguously demonstrate, that the pristine noncentrosymmetric bulk 4Ha-NbSe2 polytype significantly violates the Pauli limit.

2018年4月13日 · Using first-principles calculations, we identify the ground state 3 × 3 CDW atomic structure of monolayer NbSe 2, which is characterized by the formation of triangular Nb clusters and shows a scanning tunnelling microscopy (STM) image and Raman CDW modes in good agreement with experiments.

Layer compounds such as NbSe2 hold a special place in the study of superconductivity because they have highly anisotropic chemical bonding and because they show charge-density wave phenomena with the atten-dant lattice instabilities.

2021年4月15日 · Here we report a two-fold rotational symmetry of the superconducting state in few-layer NbSe 2 under in-plane external magnetic fields, in contrast to the three-fold symmetry of the lattice.

2024年10月17日 · In this letter, we adopted an organic cation intercalation technique to modulate the interlayer interaction of NbSe 2 by expanding the interlayer distance, thereby making intercalated NbSe 2 behave similarly to monolayer NbSe 2.
