Abstract
- The bulk moduli of PbS$_{x}$Se$_{1-x}$, PbS$_{x}$Te$_{1-x}$, and PbSe$_{x}$Te$_{1-x}$ have been recently determined [E. Skordas, Materials Science in Semiconductor Processing 43 (2016) 65-68] by employing a thermodynamical model, the so called $cB\Omega$ model, which has been found to give successful results in several applications of defects in solids. Here, we suggest an alternative procedure for this determination which combines the $cB\Omega$ model with the modified Born theory. The results are in satisfactory agreement with those deduced independently by the generalized gradient approximation approach.<br />Comment: 11 pages, 1 figure
