Massive Dirac Fermions and Strong Shubnikov-de Haas Oscillations in Topological Insulator Sm,Fe:Bi2Se3 Single Crystals
Weiyao Zhao, Chi Xuan Trang, Qile Li +9
Topological insulators (TIs) are emergent materials with unique band structure, which allow the study of quantum effect in solids, as well as contribute to high performance quantum…
Possible Excitonic Insulating Phase in Quantum-Confined Sb Nanoflakes
Zhi Li, Muhammad Nadeem, Zengji Yue +3
In the 1960s, it was proposed that in small indirect band-gap materials, excitons can spontaneously form because the density of carriers is too low to screen the attractive Coulomb…
Magneto-transport and electronic structures in MoSi bulks and thin films with different orientations
W. Afzal, F. Yun, Z. Li +8
We report a comprehensive study of magneto-transport properties in MoSi bulk and thin films. Textured MoSi thin films of around 70 nm were deposited on silicon substrates w…
Weak localization and anti-localization in rare earth doped topological insulators
Zengji Yue, Kirrily Rule, Zhi Li +7
We study magneto-transport phenomena in two rare-earth doped topological insulators, SmxFexSb2-2xTe3 and SmxBi2-xTe2Se single crystals. The magneto-transport behaviours in both com…
Spin gapless semiconductors
Zengji Yue, Zhi Li, Lina Sang +1
Spin gapless semiconductors (SGSs) are a new class of zero gap materials which have a fully spin polarised electrons and holes. They bridge zero gap materials and half-metals. The…
Modulation of crystal and electronic structures in topological insulators by rare-earth doping
Zengji Yue, Weiyao Zhao, David Cortie +3
We study magnetotransport in a rare earth doped topological insulator, Sm0.1Sb1.9Te3 single crystals, under magnetic fields up to 14 T. It is found that that the crystals exhibit S…
Giant and Linear Magnetoresistance in Liquid Metals at Ambient Temperature
Xiaolin Wang, Feixiang Xiang, David Cortie +4
Disorder-induced magnetoresistance has been reported in a range of solid metals and semiconductors, however, the underlying physical mechanism is still under debate because it is d…
Quantum Oscillations in iron-doped topological insulator Sb2Te3 crystals
Weiyao Zhao, David Cortie, Lei Chen +3
We investigated the magnetotransport properties of Fe-doped topological insulator Sb1.96 Fe0.04Te3 single crystals. With doping, the band structure changes significantly and multip…
Photo-induced change of refractive index and transparency in Bi2Te3 films
Zengji Yue, Qinjun Chen, Amit Sahu +2
We report on an 800 nm femtosecond laser beam induced giant refractive index modulation and enhancement of near-infrared transparency in topological insulator material Bi2Te3 thin…
Thermoelectric signals of state transition in polycrystalline SmB6
Zengji Yue, Qinjun Chen, Xiaolin Wang
Topological Kondo insulator SmB6 has attracted quite a lot of attentions from condensed matter physics community. A number of unique electronic properties, including low- temperatu…
Semimetal-semiconductor transition and giant linear magnetoresistances in three-dimensional Dirac semimetal Bi0.96Sb0.04 single crystals
Z. J. Yue, X. L. Wang, S. S. Yan
Three-dimensional (3D) Dirac semimetals are new quantum materials and can be viewed as 3D analogues of graphene. Many fascinating electronic properties have been proposed and reali…
Defects induced ferromagnetism in plasma-enabled graphene nanopetals
Z. J. Yue, D. H. Seo, K. Ostrikov +1
Ferromagnetism in graphene is fascinating, but it is still a big challenge for practical applications due to the weak magnetization. In order to enhance the magnetization, here, we…
