The Synthesis of the Fe3O4 Nanoparticles and the Analysis of the Current-Voltage Measurements on Au/Fe3O4/p-Si Schottky Contacts in a Wide Temperature Range
Özet
The iron oxide (Fe3O4) magnetic nanoparticles were synthesized via the organic solution phase method and used for the fabrication of the Au/Fe3O4/p-Si rectifying device. The variation in electrical characteristics of the Au/Fe3O4/p-Si Schottky contacts was investigated as a function of temperature using current-voltage (I-V) measurements in the temperature range of 40 K to 370 K (-233 A degrees C to 97 A degrees C). The I-V characteristics of the contacts indicated extremely strong temperature dependence. The double distribution of barrier heights was found in the Fe3O4/p-Si Schottky diodes from the I-V-T measurements. The Schottky barrier height (I broken vertical bar(b)) increases with the increasing temperature, while the ideality factor n decreases. The nonlinearity in the activation energy plot was observed, which is attributed to barrier inhomogeneities by assuming a Gaussian distribution of barrier heights at the Fe3O4/p-Si interface. The Richardson constant measured from the temperature-dependent I-V characteristics is 2.99 A/K-2 cm(2), which is lower than the ideal value.
