The molecular diodes developed by a team led by Latha Venkataraman, from Columbia University, perform 50 times better than all prior designs. "Our new approach created a single-molecule diode that has a high (over 250) rectification and a high "on" current (0.1 micro Ampere)," said Venkataraman. "Constructing a device where the active elements are only a single molecule has long been a tantalising dream in nanoscience," said Venkataraman.
