The physics of quantum materials is dictated by many-body interactions and mathematical
concepts such as symmetry and topology that have transformed our understanding of matter …

Epitaxial engineering of solid state heterointerfaces is a leading avenue to realizing
enhanced or novel electronic states of matter. As a recent example, bulk FeSe is an …

The Majorana fermion, which is its own antiparticle and obeys non-Abelian statistics, plays a
critical role in topological quantum computing. It can be realized as a bound state at zero …

Almost a decade has passed since the serendipitous discovery of the iron-based high
temperature superconductors (FeSCs) in 2008. The fact that, as in the copper oxide high …

FeSe layer-based superconductors exhibit exotic and distinctive properties. The undoped
FeSe shows nematicity and superconductivity, while the heavily electron-doped K x Fe2− y …

Monolayer FeSe films grown on SrTiO 3 (STO) substrate show superconducting gap-
opening temperatures (T_ c T c) which are almost an order of magnitude higher than those …

The origin of enhanced superconductivity over 50 K in the recently discovered FeSe
monolayer films grown on SrTiO3 (STO), as compared to 8 K in bulk FeSe, is intensely …

Raising the superconducting transition temperature to a point where applications are
practical is one of the most important challenges in science. In this review, we aim at gaining …

We have developed a field-effect transistor (FET) device using a solid ion conductor (SIC) as
the gate dielectric, which can tune the carrier density of FeSe by driving lithium ions in and …
