Ab initio structure searching random live functional-theory-density (DFT) to calculate energy and scientific limitations in our current structure, search, there are several research Ab initio to random searching structure used in the calculation of the structure, which has been an interesting, and sometimes the results are likely to discover new material. For example, RJ and CJ Needs Pickard (2006) presents the structure of the silane at high pressure (High-Pressure Phases of Silane) by removing the two remember SiH_4 nuan units (two to eight Atomic Atomic H Si) structure, 100 random structure, found that a structure of C2/c at a pressure of approximately 262.5 SiH_4 GPa (Figure 1). Stable (stable structure) and the Density of values estimated from the state that power level (Fermi energy level), FIR, signifying that the C2/c structure may be, it is possible to structure a ' vital ' (Superconductor) at high temperatures.
