GaInP nanofibers were formed on n-Si substrates by electrospinning method, using constant voltage (25 kV), height (6 cm), and flow rate (0.3 ml/h) during various process times (of 10, 20, 25 minutes). Characterization of the prepared samples was performed by X-ray diffraction, differential scanning calorimetry/thermal gravimetric analysis, scanning electron microscopy, and energy dispersive X-ray spectrometry. Furthermore, the current-voltage measurements of the GaInP/n-Si samples have been carried out. The obtained results show that I-V characteristics of all GaInP/n-Si samples fabricated with three thicknesses of GaInP layers are rather in a good agreement with the theory and that they exhibit rectifying properties.
