Southampton engineers set new record for world's fastest transistor

17.08.2006
Engineers in the School of Electronics and Computer Science have developed a method to make bipolar transistors twice as fast as current devices.

Bipolar transistors are solid state semiconductor devices used in mobile phones and various wireless systems.

According to Professor Peter Ashburn who undertook this research in collaboration with STC Microelectronics, the researchers used a standard silicon bipolar technique with fluorine implants to deliver a record fT of 110 GHz which is twice as fast as the current record.

‘By using fluorine implants, the transistor can operate at a higher frequency which means it will be twice as fast as it was before,’ said Professor Ashburn.

The fluorine implants are used to suppress boron diffusion in the base of the transistor which means that the base width is narrower, allowing electrons to travel across it faster.

‘This means that the electronics industry will be able to achieve better performance at little extra cost,’ Professor Ashburn commented.

Professor Ashburn and his team believe that there is scope to reduce the boron diffusion by a further 50 per cent and they are currently monitoring how the fluorine behaves and looking at whether there are other materials that will also enable this diffusion.

‘We have already beaten the world record,’ commented Professor Ashburn. ‘We have just improved the performance of silicon to a level which was only previously possible with silicon geranium.’

Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.

While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...

Im Focus: Designing Architecture with Solar Building Envelopes

Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.

As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...
