A Nanoscale Shape Memory Oxide
Jinxing Zhang, Xiaoxing Ke, Gaoyang Gou +9
Stimulus-responsive shape memory materials have attracted tremendous research interests recently, with much effort focused on improving their mechanical actuation. Driven by the ne…
Weak Topological Insulators in PbTe/SnTe Superlattices
Gang Yang, Junwei Liu, Liang Fu +2
It is desirable to realize topological phases in artificial structures by engineering electronic band structures. In this paper, we investigate superlattice…
Weak topological insulators induced by the inter-layer coupling: A first-principles study of stacked Bi2TeI
Peizhe Tang, Binghai Yan, Wendong Cao +3
Based on first-principles calculations, we predict Bi2TeI, a stoichiometric compound synthesized, to be a weak topological insulator (TI) in layered subvalent bismuth telluroiodide…
Mass acquisition of Dirac fermions in Cr-doped topological insulator Sb2Te3 films
Yeping Jiang, Zhi Li, Canli Song +7
We introduce time-reversal-symmetry breaking by doping Cr atoms into the topmost quintuple layer or into the bulk of Sb2Te3 thin films. We find that even at a high Cr-doping level…
On the electronic structure of silicene on Ag substrate: strong hybridization effects
Seymur Cahangirov, Martha Audiffred, Peizhe Tang +4
The electronic structure of the recently synthesised (3x3) reconstructed silicene on (4x4) Ag(111) is investigated by first-principles calculations. New states emerge due to the st…
Surface States of Topological Crystalline Insulators in IV-VI Semiconductors
Junwei Liu, Wenhui Duan, Liang Fu
Topological crystalline insulators (TCI) are new topological phases of matter protected by crystal symmetry of solids. Recently, the first realization of TCI has been predicted and…
