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 ...

Boost converter drives LED backlights and dims 100:1

Diodes has introduced a boost converter that can supply constant voltage or constant current to drive backlights, with a dimming ratio of 100:1. Called AL3353, it has an input voltage of 9V to 40V – maximum output voltage is dependent on the external mosfet used as a power switch Dimming is internally analogue, controlled by ...

Sat nav module adds inertial navigation for self-driving cars

U-blox is planning to inertial dead-reckoning to satellite-based signals to improve navigation in locations with poor reception – like challenging urban environments. To be implemented in ZED-F9K – samples planned from July – will be a multi-band GNSS (global navigation satellite system) receiver, inertial sensors (3d accelerometer, 3d gyroscope), signal processing algorithms and correction services ...
