presents the structure of High-Pressure Phases of Silane. (High-Pressure Phases of Silane) by SiH_4 an amount of two units (Two Si atoms H eight atoms) were assigned randomly to the 100 structure, that structure C2/c of SiH_4 at a pressure of about 262.5 GPa (Figure 1) Stable (stable structure) and the estimation Density of state-level energy Fermi (Fermi energy level) indicates that the structure C2/c may be possible to structure a conductor. Uttermost (Superconductor) at high temperatures.
