The influence of electron-doping on the ground state of (Sr{1-x}La{x})2IrO4
Xiang Chen, Tom Hogan, D. Walkup +11
The evolution of the electronic properties of electron-doped (Sr{1-x}La{x})2IrO4 is experimentally explored as the doping limit of La is approached. As electrons are introduced, th…
Ripple modulated electronic structure of a 3D topological insulator
Yoshinori Okada, Wenwen Zhou, D. Walkup +3
3D topological insulators, similar to the Dirac material graphene, host linearly dispersing states with unique properties and a strong potential for applications. A key, missing el…
Visualizing Landau levels of Dirac electrons in a one dimensional potential
Yoshinori Okada, Wenwen Zhou, Chetan. Dhital +5
Using scanning tunneling spectroscopy we have measured the response of Dirac electrons in a magnetic field to the presence of a well-defined smoothly varying 1D periodic potential.…
First-order melting of a weak spin-orbit Mott insulator into a correlated metal
Tom Hogan, Z. Yamani, D. Walkup +7
The electronic phase diagram of the weak spin-orbit Mott insulator (Sr(1-x)Lax)3Ir2O7 is determined via an exhaustive experimental study. Upon doping electrons via La substitution,…
One-dimensional channel for Dirac electrons in a 3D topological insulator
Yoshinori Okada, Wenwen Zhou, Chetan. Dhital +5
Topological insulators represent a new state of matter where the topological nature of the bulk bands dictates the existence of a surface state with unique properties. These materi…
