We investigated highly (100)-oriented PZT films directly grown on Pt films coated on RuO2/SiO2/Si substrates via sputtering method. By controlling the preferred (100) orientation volume of the Pt films, we confirmed the effectiveness of high (100) orientation of Pt films suitable for the growth of highly (100)-oriented PZT films.

The study assesses the impact of foreign direct investment (FDI) and institutional quality on the environment, while also determining the role of institutional quality in the environmental effects of FDI in developing Asian countries. By analyzing panel data from 10 developing Asian economies for the period 1996-2021 using the System Generalized Method of Moments, the research finds evidence confirming the negative impact of FDI on environmental quality in these countries.
