Procedure for carrier profiling in nanowire-based transistors
Imec researchers have developed a methodology to quantitatively map the distribution of active dopants in confined 3D-volumes. This is an important step towards in-depth understanding of transistors based on semiconductor nanowires. The new methodology is based on high-vacuum scanning spreading resistance microscopy (HV-SSRM).

Improving solar cells with the microelectronics toolbox
To make solar energy generation cost-effective, the PV industry has to reduce its manufacturing costs well below 1 euro/Wp. This holds for all PV technologies. To reach that ambitious goal, the crystalline Si based PV industry will have to increase the solar cell's efficiency while at the same time reducing the amount of high-purity Si that is used.

Coming to TV screens of the future: A sense of smell
Today's television programs are designed to trigger your emotions and your mind through your senses of sound and sight. But what if they could trigger a few more? What if you could smell or taste the cheesy slices of pizza being eaten by your favorite characters on TV? Is it possible? Would audiences enjoy the experience? Would advertisers jump on the opportunity to reach consumers in a new way?
