Molecular electronics

Back under control

To some researchers, the goal of molecular electronics is to develop cheaper and higher-performance alternatives to conventional silicon-based technology. To others, it is the exploration of entirely new possibilities opened up by the different properties and phenomena exhibited by devices constructed at the molecular level. Steady progress is being made on understanding how and if these goals can be achieved.
