Mechanosynthetic tools for a atomic-scale fabrication
View Patent ↗The present invention is directed to methods for the synthesis of products via mechanosynthesis, including bootstrap means to go from atomically-imprecise to atomically-precise tools, methods for determining reaction sequences for workpieces, and methods for creating new reactions, reaction sequences and tips.
1. A method of mechanosynthesis using a first tip and a second tip, wherein said first tip and said second tip each comprise a device including one or more active atoms whose bonding pattern or electronic state is altered during a mechanosynthetic operation and one or more support atoms whose bonding pattern or electronic state is not altered during a mechanosynthetic reaction, said method comprising:
binding feedstock to said first atomically-precise tip;
applying sufficient force to said feedstock with a second atomically-precise tip using strain to materially distort the bond geometry between said feedstock and said first atomically-precise tip; thereby increasing or decreasing the affinity of said feedstock for said first atomically-precise tip.
2. The method of claim 1 wherein said feedstock comprises an atom selected from the group consisting of Al, B, Be, Br, C, Cl, F, Ge, H, Ir, Li, Mg, N, Na, O, P, S, and Si.
3. A system for performing a mechanosynthetic reaction using a first tip and a second tip, wherein said first tip and said second tip each comprise a device including one or more active atoms whose bonding pattern or electronic state is altered during a mechanosynthetic operation and one or more support atoms whose bonding pattern or electronic state is not altered during a mechanosynthetic reaction, said system comprising:
said first atomically-precise tip, wherein said first atomically-precise tip is under positional control;
said second atomically-precise tip, wherein said second atomically-precise tip is under positional control;
feedstock;
means to bond said feedstock to said first atomically-precise tip;
means to use strain to materially alter the bond geometry between said feedstock and said first atomically-precise tip by applying force from said second atomically-precise tip; and
an atomically-precise workpiece to which feedstock is mechanosynthetically reacted.
4. The system of claim 3 wherein said feedstock comprises an atom selected from the group consisting of Al, B, Be, Br, C, Cl, F, Ge, H, Ir, Li, Mg, N, Na, O, P, S, and Si.
