Title: Optical properties of (Bi _1-x In _x ) ₂ Se ₃ thin films

Abstract

Bi₂Se₃ is a topological insulator with unique optical properties, including linearly-dispersing surface states. Many of the proposed device applications for Bi₂Se₃ require a lattice-matched trivially-insulating component. It is known that (Bi_1-xIn_x)₂Se₃ is a trivial band insulator for moderate indium concentrations. In this paper, we grow and characterize the optical properties of (Bi_1-xIn_x)₂Se₃ films with varying indium concentrations. We find that the lattice constant and optical bandgap for (Bi_1-xIn_x)₂Se₃ varies linearly with concentration. We perform infrared reflection measurements as a function of polarization and angle, enabling us to model the permittivity for these materials. Again, we find that most parameters vary linearly with concentration. Our results for the pure end members are consistent with the literature values. This is the first report of optical values for the intermediate compounds, which are likely to be integral components of future topological insulator optical devices.

Growth of high-quality Bi₂Se₃ topological insulators using (Bi_1-xIn_x) ₂Se₃ buffer layers

Journal Article Wang, Yong ; Ginley, Theresa P. ; Law, Stephanie - Journal of Vacuum Science and Technology B

Here, the authors first report on the optimum growth parameters for Bi_1-xIn_x) ₂Se₃ alloys of arbitrary composition using molecular beam epitaxy. It is found that smooth, single-phase films can only be obtained by using a sequential growth and annealing method to seed the film, after which normal codeposition growth can be used. The topological insulator Bi₂Se₃ is then grown on top of various (Bi_1-xIn_x) ₂Se₃ buffers and the electrical properties measured. For Bi₂Se₃ films grown on high-quality buffer layers, the mobility is greatly enhanced and the carrier density reduced compared to growth directly on sapphire substrates, indicating a significant improvementmore »« less

Ultrafast Carrier–Lattice Interactions and Interlayer Modulations of Bi₂Se₃ by X-ray Free-Electron Laser Diffraction

Journal Article Kim, Sungwon ; Kim, Youngsam ; Kim, Jaeseung ; ... - Nano Letters

We report as a 3D topological insulator, bismuth selenide (Bi₂Se₃) has potential applications for electrically and optically controllable magnetic and optoelectronic devices. Understanding the coupling with its topological phase requires studying the interactions of carriers with the lattice on time scales down to the sub-picosecond regime. Here we investigate the ultrafast carrier-induced lattice contractions and interlayer modulations in Bi₂Se₃ thin films by time-resolved diffraction using an X-ray free-electron laser. The lattice contraction depends on the carrier concentration and is followed by an interlayer expansion accompanied by oscillations. Using density functional theory (DFT) and the Lifshitz model, the initial contraction canmore »« less

Observation of cyclotron resonance and electron-phonon coupling in surface states of the bulk-insulating topological insulator Cu_0.02Bi₂Se₃

Technical Report Wu, Liang ; Tse, Wang-Kong ; Morris, C. M. ; ...

We have utilized magneto-optical time-domain spectroscopy to investigate the low frequency optical response of topological insulator Cu_0.02Bi₂Se₃ and Bi₂Se₃ films. With both field and frequency depedence, such experiments give sufficient information to measure the mobility and carrier density of multiple conduction channels simultaneously. We observe sharp cyclotron resonances (CRs) in both samples. The small amount of Cu substitution into the Cu_0.02Bi₂Se₃ induces a true bulk insulator with only a single conduction channel with total sheet carrier density 4.9 x 10¹²/cm² and mobility as large as 4000 cm²/V s. This is consistent with pure topological surface state (TSSs) conduction with amore »« less

Growth and characterization of molecular beam epitaxy-grown Bi{sub 2}Te{sub 3−x}Se{sub x} topological insulator alloys

We report a systematic study on the structural and electronic properties of Bi{sub 2}Te{sub 3−x}Se{sub x} topological insulator alloy grown by molecular beam epitaxy (MBE). A mixing ratio of Bi{sub 2}Se{sub 3} to Bi{sub 2}Te{sub 3} was controlled by varying the Bi:Te:Se flux ratio. X-ray diffraction and Raman spectroscopy measurements indicate the high crystalline quality for the as-grown Bi{sub 2}Te{sub 3−x}Se{sub x} films. Substitution of Te by Se is also revealed from both analyses. The surfaces of the films exhibit terrace-like quintuple layers and their size of the characteristic triangular terraces decreases monotonically with increasing Se content. However, the triangularmore »« less

Structural properties of Bi{sub 2−x}Mn{sub x}Se{sub 3} thin films grown via molecular beam epitaxy

Journal Article Babakiray, Sercan ; Johnson, Trent A. ; Borisov, Pavel ; ... - Journal of Applied Physics

The effects of Mn doping on the structural properties of the topological insulator Bi{sub 2}Se{sub 3} in thin film form were studied in samples grown via molecular beam epitaxy. Extended x-ray absorption fine structure measurements, supported by density functional theory calculations, indicate that preferential incorporation occurs substitutionally in Bi sites across the entire film volume. This finding is consistent with x-ray diffraction measurements which show that the out of plane lattice constant expands while the in plane lattice constant contracts as the Mn concentration is increased. X-ray photoelectron spectroscopy indicates that the Mn valency is 2+ and that the Mnmore »« less
