dc.description.abstractNanocrystal (NCs) pyrite FeS2 were synthesized on indium thin oxide (ITO) substrate by using thermal reaction of iron-oleyamine complexes with sulfur in olayamine. The structural and optical characterizations of FeS2 NCs were investigated and the effect of annealing temperature on thin film properties was discussed. The Scanning Electron Microscope (SEM) images shows that FeS2 films have between 25 nm and 100 nm diameter and as the annealing temperature on the thin film increased, the particle size increased. The absorption spectrums show that FeS2 NCs have direct band gap between 1.27 and 2.04 eV which is much higher than that of bulk FeS2 (0.95 eV). The changes of particle size can be attributed to the different interactions of surface energy and interface energy at different annealing temperatures. Current-Voltage characteristics show that NCs FeS2 has high conductivity and it was found that when annealing temperature of thin films increases, conductivity decreases. The surface photo voltage (SPVs) of FeS2 films was studied to explore their potential in photovoltaic application as well.en_US
