Broadband photodetectors with self-driven functions have attracted intensive scientific
interest due to their low energy consumption and high optical gain. However, high …

The interface between two different materials can show unexpected quantum phenomena.
In this study, we used molecular beam epitaxy to synthesize heterostructures formed by …

Over the last decade, the possibility of realizing topological superconductivity (TSC) has
generated much excitement. TSC can be created in electronic systems where the …

The development of superconducting materials has attracted significant attention not only for
their improved performance, such as high transition temperature (TC), but also for the …

Well-established knowledge about inversion-symmetric Bi2Te x Se3–x topological
insulators characterizes the promising new-generation quantum device. Noticeably, the …

Abstract 2D materials provide an ideal platform to explore novel superconducting behavior
including Ising superconductivity, topological superconductivity and Majorana bound states …

It is challenging to grow an epitaxial 4-fold compound superconductor (SC) on a 6-fold
topological insulator (TI) platform due to the stringent lattice-matching requirement. Here, we …

Using the tight-binding Bogoliubov–de Gennes formalism, we describe the influence of the
surface potential on the superconducting critical temperature at the surface. Surface details …

Epitaxial Fe (Te, Se) thin films have been grown on various substrates but never been grown
on magnetic layers. Here we report the epitaxial growth of fourfold Fe (Te, Se) film on a …

Spin-helical Dirac Fermions at a doped topological insulator's boundaries can support
Majorana quasiparticles when coupled with s-wave superconductors, but in n-doped …
