Logical design of a defect-tolerant circuit
(a) shows a “fat tree” architecture in which every member of a logical level of the tree hierarchy can communicate with every member at the next level; in the case of a defective component, this structure enables one to route around and avoid the defect;
(b) shows how this architecture is implemented using cross bars, which are very regular structures and look like something that can be built chemically.

Atomic structure of one of the molecular switches
• The switch can be closed electronically in a solid-state circuit by applying the appropriate voltage across the molecule (Balzani et al. 1998; Credi et al. 1997).

• This molecule conducts via resonant tunneling through unoccupied molecular orbitals when it is in its reduced chemical state (switch closed), but it is a tunneling barrier in its oxidized state (switch open).

I-V of a large number of molecular switches
• This portion of the I-V curve is highly reproducible until the potential across the molecule exceeds +1 V.
• This voltage irreversibly oxidizes the switches, and after this process, applying a negative voltage results repeatedly in a “small” current, demonstrating that the switch is open.
Source: IWGN (1999/09)
• Initially, the molecular switches are closed, and applying a negative voltage across the molecules results in a “large” current flow that varies exponentially with the magnitude of the applied voltage.

Models for 3” self-assembled robots
• Three-inch-diameter self-assembled robots mark the spot where an unexploded mine rests under the surface.
• Such robots are cheap, solar-powered, and have no processor to make application or miniaturization difficult.
