Abstract

Diluted magnetic semiconductors (DMSs) have always been of great interest to study due to their wide applications in spintronics. This research was carried out to study the influence of different hydrogen gas flow rates annealing on the physical properties of Fe doped indium oxide. In 1.92 Fe 0.08 O 3 thin films were prepared by a sol-gel method and followed by a spin coating technique. Different flow rates of hydrogen gas were applied during the annealing process. All samples showed high orientation along the (222) direction and exhibit a polycrystalline structure. Grain size increased as the flow rate increased due to the stronger reduction of H 2 . FTIR studies showed the existence of an O-H bond in the range of 3000 - 4000 cm -1 and it was caused by the flow of H 2 gas during the annealing process. The resistivity of In 1.92 Fe 0.08 O 3 thin films decreased and the carrier concentration increased with increasing hydrogen flow rates. This work has significance on the size-dependent properties and the chemical bonding in Fe doped In 2 O 3 films.
