     in the present study, zr x la1−x o y amorphous nanostructures were prepared by the sol–gel method such that the zr atomic fraction (x) ranged from 0% to 70%. an analytical model is described for the dielectric constant (k) of zr x la1−x o y nanostructures in a metal–oxide–semiconductor (mos) device. the structure and morphology of zr x la1−x o y film was studied using x-ray diffraction, scanning electron microscopy, atomic force microscopy, and transmission electron microscopy. elemental qualitative analysis was performed using energy-dispersive x-ray spectra and a map that confirmed the findings. preliminary information on the influence of thermal annealing on the morphological control of zr x la1−x o y amorphous nanostructures is presented. the dielectric constant of the crystalline zr0.5la0.5o y thin film is about 36. electrical property characterization was performed using a metal–dielectric–semiconductor structure via capacitance–voltage and current density–voltage measurements.
