Theoretical prediction of atomic and electronic structure of neutral Si6 Om (m=1-11) clusters

In this paper we found the most stable structures of silicon-oxide clusters of Si6 Om (m=1-11) by using the genetic algorithm. In this work the genetic algorithm uses a semiempirical energy function, MSINDO, to find the best cluster structures of Si6 Om (m=1-11). The best structures found were furth...
