Locally enhanced conductivity due to the tetragonal domain structure in LaAlO/SrTiO heterointerfaces
Beena Kalisky, Eric M. Spanton, Hilary Noad +14
The ability to control materials properties through interface engineering is demonstrated by the appearance of conductivity at the interface of certain insulators, most famously th…
Electron propagation from a photo-excited surface: implications for time-resolved photoemission
Shuolong Yang, Jonathan A. Sobota, Patrick S. Kirchmann +1
We perform time- and angle-resolved photoelectron spectroscopy on p-type GaAs(110). We observe an optically excited population in the conduction band, from which the time scales of…
Landau Level Spectroscopy of Dirac Electrons in a Polar Semiconductor with Giant Rashba Spin Splitting
Sándor Bordács, Joseph G. Checkelsky, Hiroshi Murakawa +2
Optical excitations of BiTeI with large Rashba spin splitting have been studied in an external magnetic field () applied parallel to the polar axis. A sequence of transitions be…
Discovery of a Three-dimensional Topological Dirac Semimetal, Na3Bi
Z. K. Liu, B. Zhou, Z. J. Wang +9
Three-dimensional (3D) topological Dirac semimetals (TDSs) represent a novel state of quantum matter that can be viewed as '3D graphene'. In contrast to two-dimensional (2D) Dirac…
Momentum-resolved electronic structure at a buried interface from soft x-ray standing-wave angle-resolved photoemission
A. X. Gray, J. Minár, L. Plucinski +19
Angle-resolved photoemission spectroscopy (ARPES) is a powerful technique for the study of electronic structure, but it lacks a direct ability to study buried interfaces between tw…
Direct Optical Coupling to an Unoccupied Dirac Surface State in the Topological Insulator BiSe
Jonathan A. Sobota, Shuolong Yang, Alexander F. Kemper +9
We characterize the occupied and unoccupied electronic structure of the topological insulator BiSe by one-photon and two-photon angle-resolved photoemission spectroscopy an…
