摘要：
The 0-K isotherms of the high-pressure hexagonal-close-packed and face-centered-cubic structures of silicon are computed using a linear muffin-tin orbital electron-band theory technique. Our theoretical pressure-volume data are fitted to the universal equation of state by least-squares procedures and the zero-pressure bulk modulus B0, its first pressure derivative B'0, and the zero-pressure volume V(n) are obtained. Our results are compared with the recent experimental and some earlier theoretical results.
