Аннотация:The conductivity of nanocrystalline Pt-, Pd-, and Ni-doped tin dioxide films on insulating SiO2 substrates is investigated in the temperature range 77 - 400 K. Doping allows variation of the resistance from 10(4) to 10(7) Omega. It is established that, in contrast with a Au/single-crystal SnO2 contact, the gold contacts for the nanocrystalline material are ohmic in the entire temperature range and their contribution to the conductance of all the structures investigated does not exceed 5%.
