Journal ArticleDOI
Topological surface states protected from backscattering by chiral spin texture
Pedram Roushan,Jungpil Seo,Colin V. Parker,Yew San Hor,David Hsieh,Dong Qian,Anthony Richardella,M. Z. Hasan,Robert J. Cava,Ali Yazdani +9 more
TL;DR: It is demonstrated that the chiral nature of these states protects the spin of the carriers, potentially useful for spin-based electronics, in which long spin coherence is critical, and also for quantum computing applications, where topological protection can enable fault-tolerant information processing.
Journal ArticleDOI
p -type Bi 2 Se 3 for topological insulator and low-temperature thermoelectric applications
Yew San Hor,Anthony Richardella,Pedram Roushan,Yuqi Xia,Joseph Checkelsky,Ali Yazdani,M. Z. Hasan,N. P. Ong,R. J. Cava +8 more
TL;DR: In this paper, the growth and elementary properties of $p$-type single crystals with $ab$-plane Seebeck coefficients of $+180\text{ }\ensuremath{\mu}\text{V}/ \text{K}$ at room temperature are reported.
Journal ArticleDOI
Atom-by-atom substitution of Mn in GaAs and visualization of their hole-mediated interactions
Dale Kitchen,Dale Kitchen,Anthony Richardella,Anthony Richardella,Jian-Ming Tang,Michael E. Flatté,Ali Yazdani +6 more
TL;DR: An atom-by-atom substitution technique using a scanning tunnelling microscope is described and applied to perform a controlled study at the atomic scale of the interactions between isolated Mn acceptors, which are mediated by holes in GaAs to reveal a strong dependence of ferromagnetic interaction on crystallographic orientation.
Journal ArticleDOI
Visualizing Critical Correlations Near the Metal-Insulator Transition in Ga1-xMnxAs
Anthony Richardella,Pedram Roushan,Shawn Mack,Brian B. Zhou,David A. Huse,David D. Awschalom,Ali Yazdani +6 more
TL;DR: Scanning tunneling microscopy reveals the import role of electron-electron interactions in a dilute magnetic semiconductor and shows that doping-induced disorder produces strong spatial variations in the local tunneling conductance across a wide range of energies.
Journal ArticleDOI
Coherent heteroepitaxy of Bi2Se3 on GaAs (111)B
Anthony Richardella,Duming Zhang,Joon Sue Lee,A. Koser,D. W. Rench,Andrew L. Yeats,Bob B. Buckley,David D. Awschalom,Nitin Samarth +8 more
TL;DR: In this article, the authors reported the heteroepitaxy of single crystal thin films of Bi2Se3 on the surface of GaAs by molecular beam epitaxy, and they showed that Bi 2Se3 grows highly c-axis oriented, with an atomically sharp interface with the GaAs substrate.
