摘要：

Recent experiment and theoretical studies appear to show a great deal of complexity in the high-pressure behavior of tetrahedral semiconductors. We show that the structural stability of silicon and the order of its phase transitions is identical to that of a tetrahedrally coordinated network of rigid rods with spring-loaded joints. We further show how this parameter-free model resolves the recent controversy regarding the first high-pressure phase in silicon.
