Investigation of de Haas-van Alphen and Shubnikov-de Haas quantum oscillations in PrTe3

The discovery of high mobility in quasi -two-dimensional (2D) rare-earth tritellurides has had a transformative impact on the field of quantum materials, particularly in relation to charge -density -wave phenomena. Despite significant progress, the complex electronic properties of these materials remain enigmatic, primarily due to a lack of comprehensive understanding regarding their transport characteristics. In this paper, we present a meticulous analysis of the magnetic -field -induced properties of PrTe3 in both bulk and nanoflake forms. Our investigations unveil a diverse range of distinct frequencies exhibited by the observed quantum oscillation effect. By combining angular -dependent magnetoresistance with Shubnikov-de Haas quantum oscillations, we successfully fit the data to a 1/cos (theta) dependence model, providing compelling evidence for a 2D -like Fermi surface and underscoring the pronounced 2D nature of the Fermi surface pockets. Furthermore, our findings reveal a zero Berry phase, corroborating the Lifshitz-Onsager quantization rule. Notably, we report a remarkable magnetoresistance value of 1800% in the 60 nm device, coupled with an electron mobility of 4.1x104 cm2 V-1 s-1. These exceptional outcomes are poised to stimulate heightened interest in exploring the potential of layered rare-earth tritellurides in the realm of quantum oscillation.
