Berry-Phase Breakdown and Semiclassical Reconciliation in Topological Dirac Fock-Darwin states
Ye-ping Jiang
I investigate the two-dimensional Dirac fermion analogue of artificial atoms (Fock-Darwin states, FD) in a circular n-p junction on a topological insulator surface. The FD states i…
Berry-phase switch in electrostatically-confined topological surface states
Jun Zhang, Ye-ping Jiang, Xu-Cun Ma +1
Here we visualize the trapping of topological surface states in the circular n-p junctions on the top surface of the 7-quintuple-layer three dimensional (3D) topological insulator…
Selective Trapping of Hexagonally Warped Topological Surface States in a Triangular Quantum Corral
Mu Chen, Yeping Jiang, Junping Peng +10
The surface of a three-dimensional topological insulator (TI) hosts two-dimensional massless Dirac fermions (DFs), the gapless and spin-helical nature of which yields many exotic p…
Modification of the hybridization gap by twisted stacking of quintuple layers in a three dimensional topological insulator thin film
Changyuan Zhou, Dezhi Song, Yeping Jiang +1
Twisting the stacking of layered materials leads to rich new physics. A three dimensional (3D) topological insulator film host two dimensional gapless Dirac electrons on top and bo…
Visualizing the in-gap states in domain boundaries of ultra-thin topological insulator films
Jun Zhang, Junbo Cheng, Shuaihua Ji +1
Ultra-thin topological insulators provide a platform of realizing many exotic phenomena such a Quantum spin Hall effect, Quantum anomalous Hall effect, etc. These effects or states…
Topological insulator Bi2Se3 thin films grown on double-layer graphene by molecular beam epitaxy
Can-Li Song, Yi-Lin Wang, Ye-Ping Jiang +14
Atomically flat thin films of topological insulator Bi2Se3 have been grown on double-layer graphene formed on 6H-SiC(0001) substrate by molecular beam epitaxy. By a combined study…
