A team of local scientists says it has developed a key material for ultra high-speed data telecommunications using a quantum effect device.

The team, led by Korea Advanced Institute of Science and Technology (KAIST) Professor Yang Kyung-hoon, said Tuesday that by using resonant tunnel diodes, it succeeded in developing an ultrahigh frequency oscillator circuit and a four-to-one multiplexer circuit.

The team’s ultrahigh frequency oscillator circuit can run on 170 times less energy than existing integrated circuits.

The team said that the newly developed circuit could be mass produced within three to five years.

The team’s research results will be published in the journal of the Institute of Electrical and Electronics Engineers’ Transactions on Nanotechnology.
