| Abstract | ||
| Present paper reports a theoretical study to investigate the compressional behavior of nano PbS(,,) under high pressure by using different equations of state. The pressure dependence of these parameters for three nano PbS particles of different sizes (2.6nm, 5.4nm and 8.8nm), have been calculated by using B-M EOS, m L-J EOS and S-K EOS. Obtained results are compared with available experimental data. This comparison reveals the validity of using the well-known EOSs of bulk materials such as B-M EOS and m L-J EOS further to S-K EOS which was used for studying nano materials. The effect of particle's size, under high pressure, have been investigated in present work. The overall results in this work let us put question mark about S-K EOS. | ||
