Transport Properties of KxV2O5?nH2O Nanocrystalline Films

Abstract

Abstract: Five different compositions of KxV₂O₅?nH₂O (where x=0.00, 0.0017, 0.0049, 0.0064 and 0.0091 mol) were prepared by the sol-gel process. Electrical conductivity and thermoelectric power were measured parallel to the substrate surface in the temperature range of 300-480 K. The electrical conductivity showed that all samples were semiconductors and that conductivity increased with increasing K content. The conductivity of the present system was primarily determined by hopping carrier mobility. The carrier density was evaluated as well. The conduction was confirmed to obey non-adiabatic small polaron hopping. The thermoelectric power or Seebeck effect, increased with increasing K ions content. The results obtained indicated that an n-type
semiconducting behavior within the temperature range was investigated.

Key words: Vanadium pentoxide xerogel, Nanocrystalline film, Electrical conductivity, Small polaron hopping
