Abstract

The polaron concept introduced at the beginning of the last century, by the physicist Lev Landau, has been intensely explored in a wide variety of semiconductor nanostructures with the most varied degrees of quantum confinement over the decades. The interaction of a polaron with an applied magnetic field proved to be a powerful tool for the determination of a very large number of parameters and physical phenomena of different traditional semiconductors, such as those formed by elements III-V of the periodic table. This project will be dedicated to the search for the elucidation of phenomena still open in some materials of this family, as well to the most recent and current transition metal dichalcogenides (TMDs) materials, whose magneto-polaron results are largely predicted from a theoretical perspective, but with experimental results still quite scarce. Thanks to the joining of researchers working in different fields of research, this project has the potential to build high quality TMD systems and characterize them with modern optoelectronic techniques of high spatial resolution with the necessary conditions to explore new effects associated with magneto-polarons and the non-linearity of the Zeeman effect, results that will allow us to determine new and interesting phenomena in this class of materials.
