The advantages of the combined AFM/STM technique for investigating the dielectric properties of ultrathin MeOx layers with high spatial resolution is shown. Particularly, MO2/Si (M=Hf, Zr) interface evolution upon heat treatments is explored. It is observed that vacuum annealing in the range Ò =800-900 °Ñ of ZrO2 films grown on Si results in the degradation ZrO2,HfO2 with formation of a Zr, Hf silicide layer which starts to grow from ZrO2/Si, HfO2/Si interface.
