摘要
Reactive magnetron sputtering technique using O-2/Ar gas mixture was used to deposit Gd2O3 layers. Following metallization process of Al allowed to create MIS structures, which electrical parameters (kappa, D-it, U-FB, rho, etc.) were measured using high frequency C-V equipment. Created layers exhibit high permittivity (kappa approximate to 12) at 100kHz. I-V measurements point out on maximum electric break down field E-br approximate to 0.4 MV/cm and maximum break down voltage U-br approximate to 16V. Layers were morphologically tested using AFM technique (R-alpha approximate to 0.5 divided by 2nm). Layer thicknesses as well as refractive indexes (RI approximate to 1.50 divided by 2.05) were estimated using ellipsometry measurements.
