Structural, Mechanical, and Electronic Properties of Monoclinic N2H5N3 Under Pressure

Structural, elastic, mechanical, and electronic properties of monoclinic N2H5N3 at zero and high pressure have been investigated using the plane-wave ultrasoft pseudopotential method within the density-functional theory (DFT). The pressure dependences of structural parameters, elastic constants, mechanical properties, band gaps, and density of states of monoclinic N2H5N3 have been calculated and discussed. The obtained results show that monoclinic N2H5N3 is unstable at pressures exceeding the value 126.1 GPa. The ratio of B/G and the Cauchy’s pressure indicate that monoclinic N2H5N3 behaves in ductile nature with pressure ranging from 0 to 200 GPa.
