This study developed a method for the formation of metal oxide protective layers by nm-scale ALD that improves the thermal stability of organic molecules and identified the mechanism by which oxygen promotes their thermal decomposition. The method successfully stabilised molecules at 300°C in air and under O₂ plasma conditions, outperforming conventional methods. In particular, Al₂O₃ formed a dense amorphous film and showed high heat resistance due to oxygen deprivation, as observed by 4DSTEM.
