New Laser for Computer Chips
Jülich, 19 January 2015 – Scientists from Forschungszentrum Jülich and the Paul Scherrer Institute in Switzerland in cooperation with international partners have presented the first semiconductor consisting solely of elements of main group IV. As a consequence, the germanium-tin (GeSn) laser can be applied directly onto a silicon chip and thus creates a new basis for transmitting data on computer chips via light: this transfer is faster than is possible with copper wires and requires only a fraction of the energy.

Research Topic

Semiconductor nanowires can be formed directly by using the so-called bottom-up approach. In contrast to the usual top-down method where optical or electron beam lithography is employed, this approach has the potential to simply the fabrication of low-dimensional semiconductor nanostructures enormously.

What alternatives are there to present computers based on crystals of silicon or other semiconductors? What is – from a physical point of view – the smallest possible device that can be used to perform computational processes? Is there a minimum amount of energy required for floating point operations?
