Magnetotransport and Berry phase Tuning in Gd-doped Bi2Se3 Topological Insulator Single Crystals
Lei Chen, Shuang-Shuang Li, Weiyao Zhao +6
The Berry phase is an important concept in solids, correlated to the band topology, axion electrodynamics and potential applications of topological materials. Here, we investigate…
Colossal magnetoresistance in Ti lightly-doped Cr2Se3 single crystals with layered structure
Shu-Juan Zhang, Jian-Min Yan, F. Tang +11
Stoichiometric Cr2Se3 single crystals are particular layer-structured antiferromagnets which possess noncolinear spin configuration, weak ferromagnetic moments, moderate magnetores…
Topological Insulator VxBi1.08-xSn0.02Sb0.9Te2S as a Promising n-type Thermoelectric Material
Lei Chen, Weiyao Zhaoa, Meng Li +8
As one of the most important n-type thermoelectric (TE) materials, Bi2Te3 has been studied for decades, with efforts to enhance the thermoelectric performance based on element dopi…
The Emerging Weak Antilocalization Effect in Semimetal TaNbSb Single Crystal
Lei Guo, Meng Xu, Lei Chen +5
Weak antilocalization (WAL) effect is commonly observed in 2D systems, or 3D topological insulators, topological semimetal systems. Here we report the clear sign of WAL effect in h…
Coexistence of Logarithmic and SdH Quantum Oscillations in Ferromagnetic Cr-doped Tellurium Single Crystals
Shu-Juan Zhang, Lei Chen, Shuang-Shuang Li +9
We report the synthesis of transition-metal-doped ferromagnetic elemental single-crystal semiconductors with quantum oscillations using the physical vapor transport method. The 7.7…
Antiferromagnetic topological insulating state in TbBiSbTeS single crystals
Lei Guo, Weiyao Zhao, Qile Li +13
Topological insulators are emerging materials with insulating bulk and symmetry protected nontrivial surface states. One of the most fascinating transport behaviors in a topologica…
