Investigation Of Shubnikov-De Haas Oscillations In A Crystalline Topological Insulator Snte/Sn1-Xeuxte Heterostructure

In this work, we investigated magnetotransport properties in epitaxial heterostructure of SnTe/Sn1-xEuxTe under dark and infrared light illumination. The longitudinal resistance has indicated the presence of Shubnikov-de Haas oscillations in the temperature range of 1.9-30 K. The fast Fourier transform analysis, performed under light and dark conditions, enabled us to understand the magnetotransport mechanism through the individual layers, leading to the proper address of each frequency that compound the Shubnikov-de Haas oscillations.
