BESAC Meeting November 14 – 15, 2001 The Molecular Foundry Lawrence Berkeley National Laboratory Response to BESAC Questions Daniel Chemla Advanced Light Source & Materials Sciences Division, LBNL Department of Physics, UC Berkeley

BESAC Questions  Nano  Macro  Relations to the “Energy” mission of BES  Private Sector contact, interest and support  Workload of Molecular Foundry management  Leverage

Currently: Nano  Micro  Macro Nanotube Junction In situ mechanical test in the TEM to measure the strength of a 12-nm thick carbon nanotube Great for research, but not scalable !!!!

Scenario for integrated self assembly of logic device systems A self-assembled 2D lattice with alternating rows of hairpins, with restriction site, and 4 nm nanocrystals. A. After using a restriction enzyme. B. Vertical and horizontal self-assembly of the linking tiles in the second layer using matching hairpins that have been restricted to match the sticky ends remaining on the lattice surface. C. Horizontal assembly of the remaining tiles not directly connected to the previous lattice. The darker nanocrystals would be made of material suitable for bits. D. The fully assembled lattice, after annealing to finish making the conducting wires. E.

Molecular Foundry: Leverage An investment in the Molecular Foundry will provide facility and expertise to at least 300 research groups (funded by all agencies) per year. This will spare the expense and time of each group setting up its own capability. In addition it will disseminate know-how and state of the art techniques to research institutions across the USA.
