This molecular device has a different operating principle than the traditional single-molecule rectifier, and has obvious advantages in terms of repeatability and controllability. This is another important research progress after they realize the negative differential conductance diode composed of two fullerene molecules by using single molecule manipulation.
The use of a single molecule to construct an electronic device with a specific function is one of the important research directions of nanoelectronics. The fullerene molecule is a star molecule at the nanometer level. It consists of 60 carbon atoms in a football-like shape. Its discoverers were awarded the 1996 Nobel Prize in Chemistry. In recent years, scientists have revealed the potential of fullerene molecules in the field of nanoelectronics, and it is considered to be one of the important candidates for future molecular devices. The research work of the University of Science and Technology of China has opened up new prospects for the application of fullerene molecules in the direction of nanoelectronics and molecular devices from the new idea of ​​nitrogen-substituted fullerene molecules to introduce specific doping levels.
The National Laboratory of Microscale Material Science at the University of Science and Technology of China has made important progress in the study of fullerene single molecule. They succeeded in replacing one carbon atom in a single molecule of fullerene with a nitrogen atom and successfully developed a novel single-molecular rectifier composed of only one molecule by a single electron tunneling effect.
