Abstract: Auxetic materials are highly desirable for advanced applications because of their negative Poisson's ratios, which are rather scarce in two-dimensional materials. Motivated by the elemental mutation method, we predict a new class of monolayer IV-VI… read more here.

Abstract: The [B3O6] group has attracted a lot of attention as α-BaB2O4 (α-BBO) is composed of the [B3O6] group showing a short UV cut-off edge and a large birefringence. However, it is difficult to synthesize novel… read more here.

DOI: 10.1063/5.0004273
Abstract: In the present paper, we investigate a special type of optical coupling between two electrically pumped semiconductor whispering gallery mode lasers. We fabricate microdisk lasers with a conjunction between the laser cavities, making the coupling… read more here.
