New Approaches in Information Technology

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?

These are the questions that concern the JARA-FIT researchers. The abbreviation "FIT" stands for "Fundamentals of Future Information Technology" and describes the tasks undertaken by the scientists in this JARA section.

They create the basis for the information technology of the future. To this end, on the one hand they explore the limits of today's silicon technology, for example by designing new chip architectures or increasing the mobility of the charge carriers.

On the other hand, JARA-FIT scientists also pursue other concepts for future hardware. In this way, they are also developing new materials and blueprints for nanocircuits, non-volatile storage and spintronics. They are investigating how biomolecules and quantum effects can be used for information processing.

Physicists, chemists, electrical engineers, mechanical engineers and biologists from 18 institutes and departments of RWTH Aachen University and Forschungszentrum Jülich collaborate in JARA-FIT. Together they operate facilities such as the Ernst Ruska Centre (ER-C) in Jülich, which has at its disposal the most powerful electron microscopes worldwide of the latest generation, for which ER-C has developed the technological basis.

JARA-FIT researchers have traditionally played a leading role internationally, which is not least reflected in the Nobel Prize in Physics awarded to Professor Peter Grünberg in 2007.


As part of a cooperation project between RWTH Aachen University and Forschungszentrum Jülich (JARA), a new database was created, that provides comprehensive overview of the main research areas in energy of the two institutions.
