Water means a second chance for over-looked organic semiconductors

Tiny quantities of water might be ruining potentially useful organic semiconductors, according to researchers at Linköping University, who have a way to fix it. Key to the issue are ‘traps’ – places where carriers – holes or electrons – get stuck and are unable to contribute to semiconductor action. “There are traps in all organic ...

One day heatsinks might be made of polythene

MIT engineers have fabricated polythene films that conduct heat – not as well as copper (401W/mK), aluminium (237) or aluminium nitride (140–180) but, at 62W/mK, as good as steel and better than alumina (30), and much better than normal polythene which is an insulator at ~0.4W/mK. “We think this result is a step to stimulate ...
