To investigate characterization of Zr x La 1-x O y nanocrystallites as a buffer oxide in forming the metal-oxide-semiconductor field effect transistors (MOSFETs) structure, we synthesized Zr x La 1-x O y nanocrystallites by sol–gel method. Moreover, from the solution prepared, thin films on silicon wafer substrates have been realized by "dip-coating" with a pulling out speed of 5 cm min -1. The structure, morphology, electrical properties of thin film was examined by X-ray diffraction (XRD), scanning electron microscopy (SEM), atomic force microscopy (AFM) and transmission electron microscopy (TEM) techniques. Electrical property characterization was performed with metal-oxide-semiconductor (MOS) structures through capacitance–voltage (C–V) and current density–voltage (J–V) measurements. The leakage current density was below 1.0 ×10-6 A/cm 2 at 1 MV/cm.
