Direct visualization of current induced spin accumulation in topological insulators
Yang Liu, Jean Besbas, Yi Wang +10
Charge-to-spin conversion in various material systems is the key for the fundamental understanding of spin-orbitronis as well as the development of efficient means to manipulate th…
Strong nonlinear terahertz response induced by Dirac surface states in Bi2Se3 Topological Insulator
Flavio Giorgianni, Enrica Chiadroni, Andrea Rovere +17
Electrons with a linear energy/momentum dispersion are called massless Dirac electrons and represent the low-energy excitations in exotic materials like Graphene and Topological In…
Coexistence of bulk and surface states probed by Shubnikov-de Haas oscillations in BiSe with high charge-carrier density
E. K. de Vries, S. Pezzini, M. J. Meijer +6
Topological insulators are ideally represented as having an insulating bulk with topologically protected, spin-textured surface states. However, it is increasingly becoming clear t…
Quantized Faraday and Kerr rotation and axion electrodynamics of a 3D topological insulator
Liang Wu, M. Salehi, N. Koirala +3
Topological insulators have been proposed to be best characterized as bulk magnetoelectric materials that show response functions quantized in terms of fundamental physical constan…
Tuning and Stabilizing Topological Insulator Bi2Se3 in the Intrinsic Regime by Charge Extraction with Organic Overlayers
Liang Wu, R. M. Ireland, M. Salehi +5
In this work, we use charge extraction via organic overlayer deposition to lower the chemical potential of topological insulator Bi2Se3 thin films into the intrinsic (bulk-insulati…
Towards the understanding of the origin of charge-current-induced spin voltage signals in the topological insulator BiSe
E. K. de Vries, A. M. Kamerbeek, N. Koirala +5
Topological insulators provide a new platform for spintronics due to the spin texture of the surface states that are topologically robust against elastic backscattering. Here, we r…
Observation of Dirac plasmons in a topological insulator
P. Di Pietro, M. Ortolani, O. Limaj +9
Plasmons are the quantized collective oscillations of electrons in metals and doped semiconductors. The plasmons of ordinary, massive electrons are since a long time basic ingredie…
Topological-Metal to Band-Insulator Transition in (Bi1-xInx)2Se3 Thin Films
Matthew Brahlek, Namrata Bansal, Nikesh Koirala +5
By combining transport and photo emission measurements on (Bi1-xInx)2Se3 thin films, we report that this system transforms from a topologically non-trivial metal into a topological…
