Surface vibrational modes of the topological insulator BiSe observed by Raman spectroscopy

H. -H. Kung, M. Salehi, I. Boulares +10

We present polarization resolved Raman scattering study of surface vibration modes in the topological insulator BiSe single crystal and thick films. Besides the four Raman…

Helicity dependent photovoltaic effect in Bi2Se3 under normal incident light

Jean Besbas, Karan Banerjee, Jaesung Son +7

Topological insulators (TIs) form a new class of materials with insulating bulk and surface conduction ensured by topologically protected surface states (TPSS). We investigate the…

Disorder-driven topological phase transition in Bi2Se3 films

Matthew Brahlek, Nikesh Koirala, Maryam Salehi +16

Topological insulators (TI) are a phase of matter that host unusual metallic states on their surfaces. Unlike the states that exist on the surface of conventional materials, these…

Finite-size and composition-driven topological phase transition in (BiIn)Se thin films

Maryam Salehi, Hassan Shapourian, Nikesh Koirala +3

In a topological insulator (TI), if its spin-orbit coupling (SOC) strength is gradually reduced, the TI eventually transforms into a trivial insulator beyond a critical point of SO…

Tunable inverse topological heterostructure utilizing

Matthew Brahlek, Nikesh Koirala, Jianpeng Liu +6

In typical topological insulator (TI) systems the TI is bordered by a non-TI insulator, and the surrounding conventional insulators, including vacuum, are not generally treated as…

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…
