Using Different Equations of States to Study Volume Ratio, Bulk Modulus and Energy Gap in Nano Ge Under High Pressure

This research has been used EOSs (Birch-Muranghan, Vinet, mL-J, Thomsen and Madan) to study the effect of high pressure on nano-Ge parameters by calculating compressed volume V/Vo, Bulk modulus BT, Energy gap Eg, under high pressure. All equations used showed compatibility with the experimental results for calculating V/Vo of nano-Ge under high pressure, an increase in the Bulk modulus BT with an increase in high pressure and an increase in the energy gap of nano Ge with high pressure.
