Photoconductivity in Single‐Crystal Tellurium

Structural and Photoconductivity Properties of Tellurium/PMMA Films.

Owing to the very brittle nature of tellurium powder, nanoscopic grains with an average size of 4.8 ± 0.8 nm were produced by dry vibration milling technique using a mixer/mill apparatus. A novel material was obtained by binding the nanosized tellurium grains with poly(methyl methacrylate) (PMMA) polymer. The morphology, elemental composition, and structural and optical properties of Te/PMMA fi...

Shock wave compression of singlecrystal forsterite

Hugoniot equation of state measurements have been performed on pure synthetic single-crystal forsterite (Mg•SiO4) in the pressure range 70-160 GPa (0.7-1.6 Mbar). These and earlier data for polycrystalline forsterite are compared with theoretical Hugoniots for the assemblages 2MgO (rocksalt) + SiO: (stishovite) and MgO (rocksalt) + MgSiO8 (perovskite). The densities attained by single-crystal f...

Anisotropic photoconductivity in graphene

We investigate the photoconductivity of graphene within the relaxation time approximation. In presence of the inter-band transitions induced by the linearly polarized light the photoconductivity turns out to be highly anisotropic due to the pseudospin selection rule for Dirac-like carriers. The effect can be observed in clean undoped graphene samples and be utilized for light polarization detec...

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...
