- Abstract
Fe1-xCrxSnSbO6 solid solution shows semiconducting behaviour with the activation energy decreasing from EA = 0:64 eV for x = 0:0 to EA = 0:32 eV for x = 1:0 in the intrinsic conductivity temperature region as well as the n-type conduction at room temperature. The I-V characteristics and the conductance G at 300 and 400 K showed symmetrical and nonlinear behavior in the voltage range (-100, 100 V) suggesting the electron emission over the potential barrier especially for the boundary compounds FeSnSbO6 and CrSnSbO6. These effects are discussed in the context of the energy gap Eg > 1:6 eV many times greater than the thermal energy kT.
