Scientists Create World’s First Molecular Transistor

Hey look ma, only one molecule!
A group of scientists has succeeded in creating the world’s first transistor made from a single molecule.

The group included researchers from Yale University and the Gwangju Institute of Science and Technology in South Korea.

The team, including Mark Reed, the Harold Hodgkinson Professor of Engineering and Applied Science at Yale, showed that a benzene molecule attached to gold contacts could behave just like a silicon transistor.

The researchers were able to manipulate the molecule’s different energy states depending on the voltage they applied to it through the contacts.

By manipulating the energy states, they were able to control the current passing through the molecule.


Nanoscale Sensors Powered By Stress


This scanning-electron-microscope image shows a stress-triggered transistor in cross section.

Nanoscale sensors have many potential applications, from detecting disease molecules in blood to sensing sound within an artificial ear. But nanosensors typically have to be integrated with bulky power sources and integrated circuits. Now researchers at Georgia Tech have demonstrated a nanoscale sensor that doesn’t need these other parts.

Chunks of this atom-thick material just one nanometer across can function as transistor

A leading contender to replace silicon as the basis for computing has made another step forward.

Transistors one atom thick and ten atoms wide have been made by UK researchers. They were carved from graphene, predicted by some to one day oust silicon as the basis of future computing.
