Abstract :
The authors present results of dielectric studies of holmium oxide (Ho2O3) thin films sandwiched between aluminum electrodes. The results show that the dielectric response of Al/Ho2 O3/Al structures is very similar to that obtained earlier for thin-film capacitors with rare-earth metal oxides (e.g. Dy 2O3, Yb2O3, and Tm2 O3) used as insulators. The dielectric behavior of these structures is connected with volume as well as with interfacial phenomena
