Abstract

To investigate characterization of ZrxLa1−xOy nanocrystallites as a buffer oxide in forming the metal-oxide-semiconductor field effect transistors (MOSFETs) structure, we synthesized ZrxLa1−xOy nanocrystallites by sol–gel method. Moreover, from the solution prepared, thin films on silicon wafer substrates have been realized by “dipcoating” 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/cm2 at 1 MV/cm.
