Quasi-hydrostatic equation of state of silicon up to 1 megabar at ambient temperature

Quasi-hydrostatic equation of state of silicon up to 1 megabar at ambient temperature

Abstract The isothermal equation of state of silicon has been determined by synchrotron x-ray diffraction experiments up to 105.2 GPa at room temperature using diamond anvil cells. A He-pressure medium was used to minimize the effect of uniaxial stress on the sample volume and ruby, gold and tungste...
