Abstract

In the present paper, the authors have employed the usual Tait's equation of state to study the structural and electronic properties of ZnS-nanocrystal .The Tait's equation of state has been used to analyze the unit cell compression under high pressure. Phase transition of Wurtzite of 10 nm ZnS to rock salt occurs at 16.5 GPa, which is higher than that of corresponding bulk materials. Moreover, the resulting pressure is found higher than that of corresponding bulk material, which indicates that the ZnS nanomaterial has higher hardness than its bulk material. The phase transition pressure (16.5 GPa) obtained in the present study presents a better agreement with the experimental data as compared to the previous studies which show that the transition to rock salt phase occurs at 12.4 GPa [3].
