General description

Tellurium is anon-radioactive and heaviest member of the chalcogen family. It has a widerange of oxidation states, from -2 to +6. It is widely used in the fields ofmetallurgy and electronics.

Application

Tellurium can be used as a precursor to prepare:
  • Tellurium-based nanomaterials for semiconductor application, such as CdTe nanoparticles via solvothermal synthesis.
  • Quantum dot solutions for fluorometric determination of bioactive compounds.
  • Thermoelectricmaterials, such as Cu4Mn2Te4 by the melting-quenching-SPS method.
Tellurium, in combination with potassium hydroxide, mediates the quantitative pinacolization of aromatic carbonyl compounds.

ZnTe is an important p-type semiconductor with great applications as field-effect transistors and photodetectors. In this paper, individual ZnTe nanowires based field-effect transistors was fabricated, showing evident p-type conductivity with an effect mobility of 11.3 cm(2)/Vs. Single ZnTe nanowire based
