Marwa K. Abood1, Evan. T. Salim2, Jehan A. Saimon3, Aseel Abdulkreem Hadi4.
This work presents the effect of NH4OH molarities on the electrical characteristics of Nb2O5
films prepared using the precipitation method. Hall Effect measurements proved the
formation of n-type Nb2O5 films. The carrier concentration was found to increase with
ammonium hydroxide molarities up to 12mol/L, while the carrier mobility decreased.
Resistivity-temperature measurements confirm the semiconductor behaviors of the thin
films. It also shows a decrease in the resistivity and activation energy with molarity
increasing reaching its minimum value in 12 mol /L then they increased again.
