Title: Quantum oscillations in magnetothermopower measurements of topological insulator Bi₂Te₃

Abstract

We report the magnetothermopower measurements of the nonmetallic topological insulator Bi2Te3 in magnetic fields up to 35 T. Quantum oscillations arising from surface states are observed in both thermoelectric and conductivity tensors. The inferred surface thermopower has a peak magnitude ~1 mV/K possibly as a result of surface electron and bulk phonon interaction. At the n = 1 Landau level, we resolve additional quantum oscillations signaling Landau sublevels.

Thickness dependent quantum oscillations of transport properties in topological insulator Bi{sub 2}Te{sub 3} thin films

Journal Article Rogacheva, E. I. ; Budnik, A. V. ; Sipatov, A. Yu. ; ... - Applied Physics Letters

The dependences of the electrical conductivity, the Hall coefficient, and the Seebeck coefficient on the layer thickness d (d = 18−600 nm) of p-type topological insulator Bi{sub 2}Te{sub 3} thin films grown by thermal evaporation in vacuum on glass substrates were obtained at room temperature. In the thickness range of d = 18–100 nm, sustained oscillations with a substantial amplitude were revealed. The observed oscillations are well approximated by a harmonic function with a period Δd = (9.5 ± 0.5) nm. At d > 100 nm, the transport coefficients practically do not change as d is increased. The oscillations of the kinetic properties are attributed to the quantum size effects due to themore »« less

Thermoelectric properties of topological insulator Bi{sub 2}Te{sub 3}, Sb{sub 2}Te{sub 3}, and Bi{sub 2}Se{sub 3} thin film quantum wells

Journal Article Osterhage, Hermann ; Gooth, Johannes ; Hamdou, Bacel ; ... - Applied Physics Letters

The thermoelectric (TE) figure of merit ZT of topological insulator Bi{sub 2}Te{sub 3}, Sb{sub 2}Te{sub 3}, and Bi{sub 2}Se{sub 3} thin film quantum wells is calculated for thicknesses below 10 nm, for which hybridization of the surface states as well as quantum confinement in the bulk are individually predicted to enhance ZT. Here, the question is addressed what ZT can be expected from coexisting surface and bulk states in such quantum wells. It is demonstrated that the parallel contributing bulk and surface channels tend to cancel each other out. This is because the surface-to-volume ratios of the thin films prevent themore »« less

Tailoring Kinetics on a Topological Insulator Surface by Defect-Induced Strain: Pb Mobility on Bi ₂ Te ₃

Journal Article Huang, Wen-Kai ; Zhang, Kai-Wen ; Yang, Chao-Long ; ... - Nano Letters

Heteroepitaxial structures based on Bi2Te3-type topological insulators (TIs) exhibit exotic quantum phenomena. For optimal characterization of these phenomena, it is desirable to control the interface structure during film growth on such TIs. In this process, adatom mobility is a key factor. We demonstrate that Pb mobility on the Bi2Te3(111) surface can be modified by the engineering local strain, ε, which is induced around the point-like defects intrinsically forming in the Bi2Te3(111) thin film grown on a Si(111)-7 × 7 substrate.

Enhanced thermoelectric efficiency in topological insulator Bi₂Te₃ nanoplates via atomic layer deposition-based surface passivation

Journal Article Chen, Jihan ; Kim, Jaehyun ; Poudel, Nirakar ; ... - Applied Physics Letters

We report in-plane thermoelectric measurements of Bi₂Te₃ nanoplates, a typical topological insulator with Dirac-like metallic surface states, grown by chemical vapor deposition. The as-grown flakes exposed to ambient conditions exhibit relatively small thermopowers around -34 μV/K due to unintentional surface doping (e.g., gas adsorption and surface oxidation). After removal of the unintentional surface doping and surface passivation by deposition of 30 nm of Al₂O₃ using atomic layer deposition (ALD), the Seebeck coefficient of these flakes increases by a factor of 5× to -169 μV/K. We believe that the ALD-based surface passivation can prevent the degradation of the thermoelectric properties causedmore »« less

Simultaneous detection of quantum oscillations from bulk and topological surface states in metallic Bi₂Se_2.1Te_0.9

Journal Article Shrestha, Keshav ; Graf, David E. ; Marinova, Vera ; ... - Philosophical Magazine (2003, Print)

Here, Shubnikov-de Haas (SdH) oscillations in metallic Bi₂Se_2.1Te_0.9 are studied in magnetic fields up to 35 Tesla. It is demonstrated that two characteristic frequencies determine the quantum oscillations of the conductivity. Angle dependent measurements and calculations of the Berry phase show that the two frequencies F₁ and F₂ describe oscillations from surface and bulk carriers, respectively. At low magnetic fields, only SdH oscillation from topological surface states can be detected whereas at high magnetic field the bulk oscillations dominate. The origin of the separation of bulk and surface SdH oscillations into different magnetic field ranges is revealed in the differencemore »« less
