Bi2Te2.85Se0.15 single crystals involving a p-n inversion layer were successfully grown by using Czachralski technique. The n-type single crystal with a low electron concentration of 1.6×10cm, which is two orders in magnitude lower than that of the starting material, was cut down across ...

The Bi2Te3Q-dot–glass nanosystem with 4 nm dots shows significant enhancement (70 times) in Verdet constant compared to the host glass and more radically better than conventional single crystal (TGG). This is the first time that such a type of unique nanosystem has been architectured and ...
High resolution Brillouin spectroscopy was used for the first time to study the dispersion and anisotropy of surface phonons in the single crystal of topological insulator Bi2Te3. Two surface acoustic waves have been observed, which distinguishes this material from other metals or nontransparent materia...
X-ray and electron diffraction reveal growth along the [110] and [210] directions and the c axis of the Bi2Te3 structure lies perpendicular to the wire axis. For the first time single crystalline, stoichiometric Bi2Te3 nanowires are grown that allow transport in the basal plane without being...

Single crystals of Bi2Te3 were synthesized from a binary melt similar to previously-published procedures [23], [24]. Bismuth beads (Aldrich, 99.999%; 1–5 mm particle size) and tellurium pellets (Aldrich purity, size) were sealed in an evacuated quartz crucible (P~1×10-3 Torr), heated...

Results Epitaxial growth of (001) Bi2Te3 films. To investigate the properties of a grain or twin boundary, it is essential to create well-defined, single-type boundaries within a single-crystal sample. Bi-crystals, where two single crystals are joined at controlled angles and orientations, ...
