It is important to solve these problems for attaining desirable high-k materials.
So, adding La2O3 to Al2O3 or adding Al2O3 to La2O3 is considered the promising material engineering to get high dielectric constant and good thermal stability materials.
Accompanied by this structural phase transition is a change of the band gap, which is important for performance of high-k gate dielectric materials.
Our results provide a guideline how to adjust composition of such composite materials used as comprehensive performance high-k dielectrics.
