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…
