Topological Insulators: Stacking Instead of Mixing
Jülich, 17 November 2015 – The overheating of computer chips is a major obstacle to the development of faster and more efficient computers. One promising remedy for this problem could be a class of materials first discovered just a few years ago: topological insulators, which conduct electricity with less resistance and heat generation than conventional materials. A team from Jülich and Aachen has now found a way to control the desired conducting properties of this type of material more precisely and reliably than ever before.

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?
