FAQ

The main goals of the REI project: "Development and experimental verification of new concepts for quantum transport characterization in complex semiconductor heterostructures" is to create a research tool for the analysis of thin-film semiconductor structures, and to develop a new methodology for magneto-transport measurements.
The subject matter that is carried out, which is related to the development of semiconductor technologies and infrared detection, lies in the special area of research interests of the MUT.
In this respect, the MUT has significant successes in the international arena, not only in the field of science, but also as a research base for Polish industry.
The need to create the discussed tool results from the demand to precisely identify the generation and recombination mechanisms, and charge carrier transport mechanisms in a semiconductor, as decisive in the efficient design of complex devices, i.e. diodes, transistors, electromagnetic radiation detectors or lasers. The starting point for the MUT and the centers cooperating with it, there are previous experiences in the field of narrow-gap materials technology, magneto-transport measurements, and calculations of the so-called mobility spectrum analysis (MSA).
