High-Pressure Investigation of the Nitrogen-Halide Systems into the Megabar Regime

Novel nitrogen-based compounds are actively sought as materials for a diverse range of technological applications, including high-energy density solids and superhard materials. As it stands, nitrogen has been studied at high pressure in conjunction with nearly all elements in the periodic table, however with a notable absence: the nitrogen-halide systems. The objective of this proposal is to fill this gap by elucidating the final chapters of the high-pressure nitrogen-based binary compounds narrative. This proposal builds on our previous successes on these systems, in which novel I-N compounds as well as I and Br allotropes were discovered. We now aim to investigate the Cl-N, Br-N, and I-N systems using laser-heated diamond anvil cells up to 180 GPa, significantly extending the pressure range of our previous experiments. The samples will be characterized by single-crystal X-ray diffraction (SCXRD).
