A half century ago, researchers at Bell Labs in Murray Hill, NJ, changed the world with their introduction of the transistor. Since then, the devices have evolved, becoming smaller, faster, and ubiquitous-finding their way into everything from computers to toasters. But today's silicon transistors are still too expensive or inflexible for some applications. Howard Katz and his colleagues at Lucent Technologies' Bell Labs hope to solve these problems using not silicon but organic chemistry.
