Ambi-chiral anomalous Hall effect in magnetically doped topological insulators
The chirality associated with broken time-reversal symmetry in magnetically doped topological insulators has important implications for the quantum transport phenomena. Here we report anomalous Hall effect stu...

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...

Nanoscale superconductivity of γ-Ga islands grown by molecular beam epitaxy
We report on the preparation and superconductivity of metastable γ-Ga islands on Si (111) substrate. The Ga grows in a typical Volmer-Weber mode at a low temperature of 110 K, resulting in formation of Ga nano...

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...

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...

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...
