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 …

Angle-resolved photoemission spectroscopy (ARPES) and scanning tunneling microscopy
(STM) have become indispensable tools in the study of correlated quantum materials. Both …

The ability in experiments to control the relative twist angle between successive layers in two-
dimensional (2D) materials offers an approach to manipulating their electronic properties; …

The superconductor iron selenide (FeSe) is of intense interest owing to its unusual
nonmagnetic nematic state and potential for high-temperature superconductivity. But its …

Single-layer FeSe film on SrTiO3 (001) has recently come to the fore as an interfacial
superconducting system, with a transition temperature that is significantly enhanced with …

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 …

The exact mechanism responsible for the significant enhancement of the superconducting
transition temperature (T c) of monolayer iron selenide (FeSe) films on SrTiO3 (STO) over …

We investigate topological properties in the Fe (Te, Se) thin films. We find that the single
layer FeTe 1− x Se x has nontrivial Z 2 topological invariance which originates from the …

We study the consequences of an electron-phonon ($ e $-$ ph $) interaction that is strongly
peaked in the forward scattering ($\mathbf {q}= 0$) direction in a two-dimensional …

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 …
