A stable compound of helium and sodium at high pressure.

Helium is generally understood to be chemically inert and this is due to its extremely stable closed-shell electronic configuration, zero electron affinity and an unsurpassed ionization potential. It is not known to form thermodynamically stable compounds, except a few inclusion compounds. Here, using the ab initio evolutionary algorithm USPEX and subsequent high-pressure synthesis in a diamond...

Electronic & Semiconducting Properties of ZnTe at Ambient and High Pressure

We report advance ab-initio computational results on the electronic structure and semiconducting properties of ZnTe which have been carried out using the first-principles tight-binding linear muffin-tin orbital method (TB-LMTO) within local density approximation (LDA). These theoretical calculations are performed to study the electronic band structures and other semiconductor’s properties like ...

Synthesis of ultra-incompressible superhard rhenium diboride at ambient pressure.

The quest to create superhard materials rarely strays from the use of high-pressure synthetic methods, which typically require gigapascals of applied pressure. We report that rhenium diboride (ReB2), synthesized in bulk quantities via arc-melting under ambient pressure, rivals materials produced with high-pressure methods. Microindentation measurements on ReB2 indicated an average hardness of 4...
