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…
Realization of Flat Band with Possible Nontrivial Topology in Electronic Kagome Lattice
Zhi Li, Jincheng Zhuang, Lan Chen +9
The energy dispersion of fermions or bosons vanishes in momentum space if destructive quantum interference occurs in a frustrated Kagome lattice with only nearest-neighbour (NN) ho…
Observation of van Hove Singularities in Twisted Silicene Multilayers
Zhi Li, Jincheng Zhuang, Lan Chen +7
Interlayer interactions perturb the electronic structure of two-dimensional materials and lead to new physical phenomena, such as van Hove singularities and Hofstadter's butterfly…
Metal-Silicene Interaction Studied by Scanning Tunneling Microscopy
Zhi Li, Haifeng Feng, Jincheng Zhuang +5
Ag atoms have been deposited on 3x3 silicene and R3xR3 silicene films by molecular beam epitaxy method in ultrahigh vacuum. Using scanning tunneling microscopy and Raman spectrosco…
