Tiniest Computers Ever!

| | Comments (0)
Physicists have applied for a patent concerning a single-molecule transistor – a device with the potential to dramatically miniaturize electronics. They call the device QuIET for the Quantum Interference Effect Transistor. Current transistors are as small as 65 nanometers while the single-molecule transistor would be approximately a single nanometer.
The physicists behind this project use aromatic molecules like benzene and attach three electrical leads to the molecule, regulating electron waves to turn the transistor on and off. While practical computing applications of the technology still need to be demonstrated and are yet a long way off, this is more exciting progress toward dramatically smaller and more powerful computing.
