| Imagine a small vial containing trillions of transistors, running at speeds measured in terahertz. Forget silicon chips constructed in a series of long, exacting steps. Chemists will mix the right ingredients under very specific conditions and the molecular electronic devices will assemble themselves! The field is called molecular electronics, or moletronics for short. Chemist Jim Tour of Rice University and physicist Mark Reed of Yale have pioneered the new technology that could spell the death of silicon in the next twenty year. Large corporations, such as IBM and Hewlett-Packard, are heavily committed to research and development and, in his final State of the Union address, President Clinton proposed spending nearly a half a billion dollars on molecular computing and nanotechnology. There is good reason to proceed. Leaders in the semiconductor industry worry about reaching the limits of silicon technology. A Pentium chip contains millions of transistors on a board barely several molecules thick. The manufacturing process requires very precise etching and quality control. Millions of molecular devices can take up the space of only one silicon transistor and run millions of times faster. The cost savings and versatility of moletronics are also enormous. A terabyte of capacity might cost less than ten cents and the product could be printed, painted, sprayed, or glued onto virtually anything. Although skeptics abound and major difficulties remain to be solved, moletronics appears to be one of the most promising scientific developments of our time.

What impact will moletronics have on existing technologies? What role should the government play in the development of molecular electronics? What challenges would such an easily applied technology pose for privacy and security? |
