Description

Thermal evolution and stability of hexagonal molybdenum diselenide were investigated using classical molecular dynamics simulations. Stillinger-Weber type potential parameters were considered for interatomic molybdenum–molybdenum, molybdenum-selenium, and selenium-selenium interactions. NPT Hoover thermodynamic ensemble was explored to check different energy-temperature variations. Radial distribution functions and structure factors were also extracted and plotted at different temperature intervals. Coefficient of volume expansion and specific heat capacity were calculated be 1.27 x 10-6 K-1 and 1.67 x 10-4 eV/K respectively. Acquired results agree well with measurements and some calculations.
