Description: 
High-k polycrystalline Pr2O3 thin films have been deposited by metal organic chemical vapor deposition (MOCVD) technique on Si(0 0 1) and 4H–SiC(0 0 0 1) substrates. MOCVD processes have been carried out from the Pr(tmhd)3 (H-tmhd= 2,2,6,6-tetramethyl-3,5-heptandione) precursor. Complete structural and morphological characterization of films has been carried out using several techniques (X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM)). Polycrystalline Pr2O3 films have been obtained and at the interface a praseodymium silicate amorphous layer has been observed on both substrates. The electrical properties of the dielectric praseodymium films have been evaluated.
