Source gated transistors, like these made on glass at Surrey University, could help deliver flexible electronics

A Surrey school student has co-authored a paper investigating components that could be important for the future of flexible electronics.

The 18-year-old studied source gated transistors, a lightweight alternative to traditional transistors.

Their usability has been questioned due to some self-heating effects.

The new research, presented at the British Science Festival and published in Scientific Reports, shows that these effects are actually minimal.

Source gated transistors (SGTs) are a more energy efficient, lightweight alternative to traditional transistors – the fundamental building blocks of electronic devices. They allow the control of colour and brightness in the pixels on a screen, among a raft of other variables.

But it had been thought that SGTs self-heating would lead to device failures.
