Toward Mechanosynthesis of Diamondoid Structures: VIII. Quantum-Chemical Molecular Dynamics Simulations of Hexagonal Silicon-IV Structure Synthesis with STM
Abstract:As originally pointed out by Drexler, members of the broad class of diamondoids can differ from diamond both in respect to bonding pattern and elemental composition. In this paper the strategy of positional mechanosynthesis of hexagonal silicon-IV structures is studied by quantum-chemical molecular dynamics simulations. The estimated mechanosynthesis conditions together with the general knowledge of silicon chemistry suggest that the hexagonal polytype Si-IV, also termed as lonsdaleite Si, is probably readily accessible by UHV-SPM tip driven mechanosynthesis.
