3. RationalYou@sinamail.com 3 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.

4. RationalYou@sinamail.com 4 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). Source: IWGN (1999/09) 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).

5. RationalYou@sinamail.com 5 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.
