THE IMPACT OF PRESSURE ON THE LATTICE CONSTANT IN THE ROCK SALT SITUATION BINARY COMPOUND AGN
Keywords:
compressibility, variables, bonds, volumeAbstract
First-principles simulations based on density functional theory (DFT) are used to study the structural, electronic, and optical properties of the Rock salt (RS) AgN bulk. When the pressure was zero, the lattice constant's magnitude was 8.23 Å, and the energy gap's quantity was 3.1 eV. However, when 20 kPa of pressure is applied, the lattice constant decreases to 6.5 Å, while the energy gap grows to 3.9 eV. Pressure generally lowers a solid's lattice constant. This occurs as a result of pressure forcing atoms closer together and decreasing the gap between them. A reduction in the lattice constant indicates that the crystal is being crushed since it represents the spacing between neighboring atoms in a crystal. Not every solid has the same impact of pressure on the lattice constant. Certain solids will compress more than others, which means that when pressure is applied, their volume will fall more dramatically. A solid's compressibility is determined by several variables, one of which is the kind of bonds that bind them together.
