DOI: 10.1007/s10909-020-02418-1
Abstract: We describe the effect of nonmagnetic impurity on the superconductivity behavior of the NdFeAsO 0.8 F 0.2 iron-based superconductor. The resistivity measurements show that the superconductivity is suppressed upon increasing the low amounts of calcium… read more here.

DOI: 10.1103/physrevb.96.140507
Abstract: Hydrogen (H)-doped LaFeAsO is a prototypical iron-based superconductor. However, its phase diagram extends beyond the standard framework, where a superconducting (SC) phase follows an antiferromagnetic (AF) phase upon carrier doping; instead, the SC phase is… read more here.

DOI: 10.1103/physrevlett.125.086401
Abstract: Quantum anomalous Hall (QAH) insulator is the key material to study emergent topological quantum effects, but its ultralow working temperature limits experiments. Here, by first-principles calculations, we find a family of stable two-dimensional (2D) structures… read more here.
