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…
Mapping the Electronic Structure of Each Ingredient Oxide Layer of High- Cuprate Superconductor Bi2Sr2CaCu2O8+δ
Yan-Feng Lv, Wen-Lin Wang, Jun-Ping Peng +11
Understanding the mechanism of high transition temperature (Tc) superconductivity in cuprates has been hindered by the apparent complexity of their multilayered crystal structure.…
Visualizing the elongated vortices in -Ga nanostrips
Hui-Min Zhang, Zi-Xiang Li, Jun-Ping Peng +10
We study the magnetic response of superconducting -Ga via low temperature scanning tunneling microscopy and spectroscopy. The magnetic vortex cores rely substantially on the Ga…
Molecular beam epitaxy growth and scanning tunneling microscopy study of TiSe ultrathin films
Jun-Ping Peng, Jia-Qi Guan, Hui-Min Zhang +5
Molecular beam epitaxy is used to grow TiSe2 ultrathin films on graphitized SiC(0001) substrate. TiSe2films proceed via a nearly layer-by-layer growth mode and exhibit two dominant…
Detection of a superconducting phase in a two-atom layer of hexagonal Ga film grown on semiconducting GaN(0001)
Huimin Zhang, Yi Sun, Wei Li +21
The recent observation of superconducting state at atomic scale has motivated the pursuit of exotic condensed phases in two-dimensional (2D) systems. Here we report on a supercondu…
Direct observation of quantum confinement of massless Dirac fermions in a topological insulator
Mu Chen, Zhen-Guo Fu, Jun-Ping Peng +9
Since the discovery of topological insulators (TIs)1,2, the peculiar nature of their chiral surface states has been experimentally demonstrated both in bulk and in film materials w…
Direct observation of high temperature superconductivity in one-unit-cell FeSe films
Wenhao Zhang, Yi Sun, Jinsong Zhang +26
Heterostructure based interface engineering has been proved an effective method for finding new superconducting systems and raising superconductivity transition temperature (TC). I…
