Composition of the PTL depends on the plasma treatment
As mentioned in the introduction, the composition of the plasma treated liquids depends on the plasma system used for their preparation (see Table 3). The plasma systems generating plasma…

Impact of halide variation on the optoelectronic properties of double perovskites
Crystal growth and structural properties
The single crystals of \(Cs_{2}AgBiCl_{6}\) and \(Cs_{2}AgBiBr_{6}\) are prepared via a slow cooling technique (Fig. 1a). This technique was based on the use of hydrochloric (HCl) and hydrobromic (HBr) acid…

Hyperbolic dispersion and low-frequency plasmons in electrides
Limitations of hyperbolic dispersion in general anisotropic crystals
We first present the reasoning why general anisotropic crystals cannot guarantee a hyperbolic dispersion. In metals, the hyperbolic plasmonic modes arise from the interaction…

Magnetic imaging under high pressure with a spin-based quantum sensor integrated in a van der Waals heterostructure
Principle of the experiment
We start by studying how the optical and spin properties of \({{{\rm{V}}}}_{{{\rm{B}}}}^{-}\) centers in hBN evolve with pressure. To this end, we rely on a monoisotopic h10BN crystal in which

Why “dry” oil wells aren’t really empty
A common problem with oil wells is that they can run dry even when sound-based measurements say there’s still oil there. A team from Penn State University used PSC’s flagship Bridges-2 supercomputer to add a time dimension to these seismic…
