A more efficient nano-diode (linking together two carbon nanotubes) has been created by GE, marking another step towards practical atomic electronics.
The new process uses electric fields rather than doping to modify the diode properties. This allows for more adaptable types of nano-circuitry, since the electric fields can be varied to alter the properties of the diode, while doping is a fixed process.
Numerous obstacles must still be… read more
