Abstract
The vacancy formation enthalpy of tungsten under the condition of intense laser irradiation and compression has been investigated from first-principles, respectively. The results show that the monovacancy formation enthalpy of tungsten tends to increase as the electronic temperature is increased, which can explain the fact that the melting process becomes more difficult under high electronic temperature. In addition, the monovacancy formation enthalpy of tungsten is found to increase from 3.198Â eV at 0Â GPa to 4.184Â eV at 100Â GPa, which results in the retardation of diffusion under the condition of compression.
