On the Band Structure of Bi2Te3

Semiconductors, 2019
For p-Bi2Te3 crystals grown by the Czochralski method, the temperature dependences of the conductivity, Hall coefficient, thermoelectric power (α), and transverse Nernst–Ettingshausen coefficient are obtained experimentally in the temperature range 77–450 K. The transmittance spectrum in the range 400–5250 cm–1 is recorded at room temperature.

Heterodiffusion of selenium in Bi2Te3

Physics Letters A, 1988
Abstract We present results for the anisotropic diffusion coefficient of selenium, isoelectronic impurity, in Bi2Te3 along the solidus. The experimental conditions permitted us to obtain a definite stoichiometric deviation, and diffusion profiles were obtained by SIMS.

Electrodeposition of Bi2Te3 films

AIP Conference Proceedings, 1994
The Bi2Te3 and its derivative compounds are very interesting materials in the field of thermoelectric refrigeration at room temperature. An electrochemical deposition that is an alternative process of the standard synthesis is developed in our laboratory.

The Tl2Te3-Bi2Te3 System

Journal of Applied Physics, 1966
The pseudobinary system Tl2Te3-Bi2Te3 was studied by means of microscopy, differential thermal analysis, and x-ray diffraction. No ternary compounds are found within the system. In particular, we do not find the compound TlBiTe3 previously reported by Borisova, Efremova, and Vlasov.

Electronic structure and thermoelectric properties of Bi2Te3 crystals and graphene-doped Bi2Te3

Thin Solid Films, 2010
The electronic structure and thermoelectric properties of Bi2Te3 single crystals and graphene-doped Bi2Te3 polycrystalline samples were investigated with the aid of first-principles calculations, X-ray diffraction, scanning electron microscopy, Rietveld refinement, and thermal and transport measurements.

Plasma Edge in Bi2Te3

Journal of Applied Physics, 1963
The reflectance minima associated with the free carrier plasma edges in p- and n-type Bi2Te3 have been observed at 78° and 300°K. The data together with the measured Hall and Seebeck coefficients have yielded combined band structure-relaxation time parameters when proper account is taken of the anisotropy.

Study of the strain-resistance properties of massive samples of Bi2Te3-Sb2Te3 and Bi2Te3-Bi2Se3

Journal of Engineering Physics, 1989
The coefficients of strain sensitivity of polycrystalline samples of ternary alloys based on bismuth and antimony chalcogenides were measured and the strain sensitivity of Peltier thermocouples of low height under real working conditions were evaluated.

Bi2Te3–Te nanocomposite formed by epitaxial growth of Bi2Te3 sheets on Te rod

Journal of Solid State Chemistry, 2006
Abstract Single-crystal Bi 2 Te 3 –Te nanocomposites with heterostructure were synthesized using a two-step solvothermal process in the presence of ethylenediaminetetraacetic acid disodium salt. The first step is the formation of the Te nanorods and the second step is to grow the Bi 2 Te 3 sheets off the Te rods surface to form the Bi 2 Te 3 –Te ...

Pulsed electrodeposition of Bi2Te3 and Bi2Te3/Te nanowire arrays from a DMSO solution

Electrochimica Acta, 2011
Abstract Dense, continuous and polycrystalline bismuth telluride (Bi 2 Te 3 ) nanowire arrays have been deposited from a DMSO solution containing Bi(NO 3 ) 3 ·5H 2 O and TeCl 4 in porous alumina templates by a pulse electrochemical method. The composition of the nanowire is dependent on the applied potential, and the composition distribution along a

Three-Dimensional Bi2Te3 Nanocrystallites Embedded in 2D Bi2Te3 Films Grown by MOCVD

Journal of Electronic Materials, 2012
Two- (2D) and three-dimensional (3D) growth of nanostructured Bi2Te3 films was performed on 4° tilt (100) GaAs substrates using a metalorganic chemical vapor deposition system. To obtain 3D Bi2Te3 crystallites embedded in 2D planar film, we alternately changed the gas flow rate in the reactor.
