[23/01/2012] Researchers at the Niels Bohr Institute have combined quantum physics and nano physics. This has led to the discovery of a new method for laser cooling semiconductor membranes. Semiconductors are vital components in many electronics, and the efficient cooling is important for future quantum computers and ultrasensitive sensors. The cooling method works paradoxically by heating the material! New Method: Cooling Semiconductor by Laser Light - read more

X-Ray Photography: High-Speed CMOS Sensors Provide Better Images

[06/01/2012] Conventional CMOS image sensors are not suitable for low-light applications such as fluorescence, since large pixels arranged in a matrix do not support high readout speeds. A new optoelectronic component developed by researchers of the Fraunhofer Institute for Microelectronic Circuits and Systems IMS (Germany) speeds up this process.

Magnon Drag Unveiled: 50-year Quest to Isolate Thermoelectric Effect is Over

( Source: COMPAMED.de )

[20/12/2011] As electrons move past atoms in a solid, their charge distorts the nearby lattice and can create a wave. Reciprocally, a wave in the lattice affects the electrons motion, in analogy to a wave in the sea that pushes a surfer riding it.
