Open AccessAnomalous superconducting proximity effect of planar Pb–RhPb2 heterojunctions in the clean limit
Interest in superconducting proximity effect has been revived by the exploitation of Andreev states and by the possible emergence of Majorana bound states at the interface. Spectroscopy of these states has bee...

Tailored Ising superconductivity in intercalated bulk NbSe2
Reducing the dimensionality of layered materials can result in properties distinct from their bulk crystals1–3. However, the emergent properties in atomically thin samples, in particular in metallic monolayer fla...

Evidence of anisotropic Majorana bound states in 2M-WS2
Searching for Majorana bound states has become an important topic because of its potential applications in topological quantum computing. 2M-phase WS2, a newly synthesized superconductor, not only presents the hi...

Disorder-induced multifractal superconductivity in monolayer niobium dichalcogenides
The interplay between disorder and superconductivity is a subtle and fascinating phenomenon in quantum many-body physics. Conventional superconductors are insensitive to dilute non-magnetic impurities, known a...

Open AccessReal-space observation of charge ordering in epitaxial La2−xSrxCuO4 films
The cuprate superconductors exhibit ubiquitous instabilities toward charge-ordered states. These unusual electronic states break the spatial symmetries of the host crystal, and have been widely appreciated as ...

Direct evidence of ferromagnetism in a quantum anomalous Hall system
Quantum anomalous Hall (QAH) systems are of great fundamental interest and potential application because of their dissipationless conduction without the need for an external magnetic field1–9. The QAH effect has ...

Superconductivity in few-layer stanene
A single atomic slice of α-tin—stanene—has been predicted to host the quantum spin Hall effect at room temperature, offering an ideal platform to study low-dimensional and topological physics. Although recent ...

Stripes developed at the strong limit of nematicity in FeSe film
A hidden stripe-type charge ordering in multilayer iron selenide films on strontium titanate, resembling that in high-temperature cuprate superconductors, could help to explain the complex behaviour of this un...

Fully gapped topological surface states in Bi2Se3 films induced by a d-wave high-temperature superconductor
By growing a topological insulator on top of a high-temperature superconducting substrate it is possible to induce superconductivity in the surface states of the topological insulator. Moreover, the pairing sy...

Full spin ahead for photoelectrons
The ability to manipulate the spin orientation of the highly spin-polarized photoelectrons ejected from topologically protected surface electrons by light polarization may pave the way for opto-spintronics app...

Phase separation and magnetic order in K-doped iron selenide superconductor
The discovery that potassium-doped iron selenide undergoes phase separation into a defect-free superconducting phase and an iron-vacancy-ordered insulating phase resolves many questions about the unusual behav...

Crossover of the three-dimensional topological insulator Bi2Se3 to the two-dimensional limit
The gapless surface states of topological insulators could enable quantitatively different types of electronic device. A study of the topological insulating Bi2Se3 thin films finds that a gap in these states open...

Superconductivity in one-atomic-layer metal films grown on Si(111)
There are many two-dimensional superconductors, but only now have monolayers of metallic atoms shown superconductivity. Grown on silicon substrates, epitaxial films of lead and indium represent the thinnest su...
