The authors report in detail on the reactive plasma etching properties of tellurium and demonstrate a high quality etching process using hydrogen, methane, and argon. Very low loss planar ridge waveguides are demonstrated. Optical losses in tellurium dioxide waveguides below 0.1 dB/cm in most of the near infrared region of the electromagnetic spectrum and at 1550 nm have been achieved—the lowes...

We present a study of the surface reactivity of a Pd/Bi2Te3 thin film heterostructure. The topological surface states from Bi2Te3, being delocalized and robust owing to their topological natures, were found to act as an effective electron bath that significantly enhances the surface reactivity of palladium in the presence of two oxidizing agents, oxygen and tellurium respectively, which is cons...

Abstract The R&D results of new tellurium-loaded liquid and plastic scintillators (TeLS TePS) for the experiments on search neutrinoless double beta decay are presented. Linear alkylbenzene polystyrene used as a scintillation base TeLS TePS, respectively. Diphenyltellurium di-2-ethylhexanoate complex compound diphenyltellurium oxide di-(2-ethylhexyl)phosphoric acid proposed tellurium-contai...

Dedicated to Professor Hubert Schmidbaur on the occasion of his 75 th birthday The reactions of Zintl ions Sn9 4− formed in ethylenediamine solutions of K2Cs2Sn9 and Rb4Sn9 with elemental tellurium have been investigated. Addition of elemental tellurium to the filtrates of these solutions leads – depending on the reaction conditions – to four different products: Compounds K0.36(1)Cs3.64(1)[SnTe...

Electrodeposition of elemental Te from [NnBu4]2[TeCl6] in a weakly coordinating solvent, dichloromethane, has been investigated. The reduction the Te(IV) complex to deposit shows very large (> 1 V) overpotential on clean Pt macrodisc electrodes and microelectrodes that is significantly reduced once deposited electrode. Corresponding studies show there no significant for deposition Te(II) comple...

This paper reports on the use of (130)Te(2) absorption lines in active laser-locking, and in frequency referencing, of the emission of a violet extended cavity diode laser with a wavelength of around 410 nm. We note the existence of closely spaced tellurium absorption lines, suitable for referencing purposes in gas sensing applications, at wavelengths below the lower limit (417 nm) of the spect...

This paper reports the fabrication and testing of Bismuth Tellurium (Bi2Te3) – Antimony Tellurium (Sb2Te3) based thermocouples using screen printing technology. In this study, screen printable thermoelectric pastes were developed and the transport properties of cured material were measured. The dimension of each planer thermoleg is 39.3 mm × 3 mm with a thickness of 67 μm for Bi2Te3 leg and 62 ...

This communication is concerned with the formation of spheroidal bodies from Bacillus megaterium strain KM, by the action of potassium tellurite in a hypertonic sucrose medium. Cells grown in sucrose-casein hydrolyzate broth (Lederberg and St. Clair, J. Bacteriol., 75, 143, 1958) were inoculated into fresh broth and aerated at 37 C for 3 to 4 hr. Potassium tellurite (final concentration 0.05 pe...

The development of metal oxide-based molecular wires is important for fundamental research and potential practical applications. However, examples of these materials are rare. Here we report an all-inorganic transition metal oxide molecular wire prepared by disassembly of larger crystals. The wires are comprised of molybdenum(VI) with either tellurium(IV) or selenium(IV): {(NH4)2[XMo6O21]}n (X=...
