Electrically tunable low-density superconductivity in a monolayer topological insulator [PDF]
Science, 2018 A monolayer of many talents Superconductors with a topologically nontrivial band structure have been predicted to exhibit exotic properties. However, such materials are few and far between. Now, two groups show that the monolayer of the material tungsten

Two‐Dimensional Materials as a Multiproperty Sensing Platform
Advanced Functional Materials, EarlyView.Various sensing modalities enabled and/or enhanced by two‐dimensional (2D) materials are reviewed. The domains considered for sensing include: 1) optoelectronics, 2) quantum defects, 3) scanning probe microscopy, 4) nanomechanics, and 5) bio‐ and chemosensing.

Zero-bias photocurrent in ferromagnetic topological insulator
Nature Communications, 2016 By magnetic-doping, the electronic band structure of a topological insulator can be significantly altered to yield functional behaviour. Here, the authors demonstrate a large photocurrent response, and its control, under zero-bias in an optimally ...

Topological crystalline insulator states in Pb(1-x)Sn(x)Se
, 2012 Topological insulators are a novel class of quantum materials in which time-reversal symmetry, relativistic (spin-orbit) effects and an inverted band structure result in electronic metallic states on the surfaces of bulk crystals.

Advanced Functional Materials, EarlyView.The study explores structural and magnetic properties of one of the most recent topological quantum materials (MnBi2Te4). The Mn‐poor structure leads to stacking faults (quintuple layer ‐ QL of Bi2Te3 formation instead of a septuple layer ‐ SL of MnBi2Te4), resulting in a coexistence between weak antiferromagnetism and ferromagnetism.

Distinct topological properties in Ce monopnictides having correlated f electrons: CeN vs. CeBi
Physical Review Research, 2020 The hitherto-studied topological nature in Ce monopnictides (CePn) has been discussed based solely on their p-d band inversion, despite the existence of f electrons.

Magnetoelectric polarizability and axion electrodynamics in crystalline insulators
, 2009 The orbital motion of electrons in a three-dimensional solid can generate a pseudoscalar magnetoelectric coupling $\theta$, a fact we derive for the single-particle case using a recent theory of polarization in weakly inhomogeneous materials.
