碩士 === 中國文化大學 === 應用化學研究所 === 91 === This study confers organic magnesium compounds adsorbed on the Si(100)-(2×1) semi-conductor surface, and compareds different structures, forms and energies. In the first chapter, we had a discussion of six for structures MgCN/Si(100), including found the [2+2] cyclo-addition of C≡N onto Si＝Si. The energies of this cyclo-addition structure is higher then other structures, due to the ring strain. We also present the result of BeCN, LiCN and NaCN on Si(100). Among which BeCN/Si(100) is much different from others. In the second chapter, we study the MgCCMg adsorptions on the Si(100)-(2×1) semi-conductor surface, and compare different structures, forms and energies, incuding [2+2], [4+2] cyclo-addition structures. The energies of [2+2] cyclo-addition is higher then other structures due to its ring strain.
