Y₂O₃

Table 2066. Properties of amorphous Y2O3. Static dielectric constant (K) 15 Conduction band (CB) offset on silicon substrate 2.3 Band gap energy (eV) 6 The cubic phase of ZrO2 is not thermodynamically stable. In practical applications, to stabilize the crystal structures, a small amount of stabilizers  (divalent or trivalent oxides of cubic symmetry) such as MgO, CaO, Y2O3, CeO2, Sc2O3 or Yb2O3 need to be added to stabilize the ZrO2 to the cubic phase.
