Lithium–tellurium batteries based on tellurium/ porous carbon composite

For the first time, lithiation/delithiation behavior of tellurium at room temperature was investigated using tellurium/porous carbon (Te/C) composite electrodes. The Te/C composite is synthesized by the infusion of liquid tellurium into a porous carbon host at the high temperature of 600 C under vacuum. Owing to the physical confinement of Te by porous carbon matrix, the Te/C electrode is capab...

Pt3Te4 nanoparticles from tellurium nanowires.

We report the synthesis of platinum telluride nanoparticles (Pt(3)Te(4) NPs) in the solution phase at room temperature using a template-assisted method. The dendrimeric aggregates formed are composed of several small units of Pt(3)Te(4) NPs of ∼4 nm diameter. Tellurium nanowires (Te NWs) are used as the template and the reducing agent in the growth of NPs which occurs due to the galvanic replac...

Investigation of tellurium - implanted silicon *

Hall and sheet-resistivity measurements as a function of temperature combined with layer removal have been used to study Si implanted with Teat energies up to 220 keY. At low doses c::S: 4 X l 0 em--'), Te has a donor level with a 140-meV activation energy. The activation energy decreases at higher Te doses and is approximately equal to zero forTe doses<: I 0 cm• At high dose levels, the number...

Photolytic preparation of tellurium nanorods.

Well-defined tellurium nanorods have been prepared by the photolysis of (t)Bu2Te2 in an aqueous micellar system incorporating dodecanethiol as an auxiliary morphology-directing agent.
