Open AccessVan der Waals polarity-engineered 3D integration of 2D complementary logic
Vertical three-dimensional integration of two-dimensional (2D) semiconductors holds great promise, as it offers the possibility to scale up logic layers in the z axis1–3. Indeed, vertical complementary field-effe...

Open AccessTransient responses of double core-holes generation in all-attosecond pump-probe spectroscopy
Double core-holes (DCHs) show remarkable and sensitive effects for understanding electron correlations and coherence. With advanced modulation of x-ray free-electron laser (XFEL) facility, we propose the forth...

Open AccessSynergistic correlated states and nontrivial topology in coupled graphene-insulator heterostructures
Graphene has aroused great attention due to the intriguing properties associated with its low-energy Dirac Hamiltonian. When graphene is coupled with a correlated insulating substrate, electronic states that c...

Open AccessUnconventional correlated insulator in CrOCl-interfaced Bernal bilayer graphene
The realization of graphene gapped states with large on/off ratios over wide do** ranges remains challenging. Here, we investigate heterostructures based on Bernal-stacked bilayer graphene (BLG) atop few-lay...

Open AccessIsospin competitions and valley polarized correlated insulators in twisted double bilayer graphene
New phase of matter usually emerges when a given symmetry breaks spontaneously, which can involve charge, spin, and valley degree of freedoms. Here, we report an observation of new correlated insulators evolve...

Open AccessCorrelated states in doubly-aligned hBN/graphene/hBN heterostructures
Interfacial moiré superlattices in van der Waals vertical assemblies effectively reconstruct the crystal symmetry, leading to opportunities for investigating exotic quantum states. Notably, a two-dimensional n...

Open AccessSpectral signatures of the surface anomalous Hall effect in magnetic axion insulators
The topological surface states of magnetic topological systems, such as Weyl semimetals and axion insulators, are associated with unconventional transport properties such as nonzero or half-quantized surface a...

Open AccessMultifunctional antiferromagnetic materials with giant piezomagnetism and noncollinear spin current
We propose a new type of spin-valley locking (SVL), named C-paired SVL, in antiferromagnetic systems, which directly connects the spin/valley space with the real space, and hence enables both static and dynamical...

Open AccessA brief exposure to cadmium impairs Leydig cell regeneration in the adult rat testis
Cadmium is an endocrine disruptor, impairing male reproduction. The objective of this study is to investigate whether cadmium affects rat Leydig cell regeneration and to dissect the underlying mechanism. Adult...
