A novel method to fabricate the memory structure of LaAlO3 nanocrystals embedded in amorphous Lu2O3 high-k dielectric by the pulsed laser deposition method using a rotating target was successfully developed. The average mean size and aerial density of the LaAlO3 nanocrystals are estimated to be about 6 nm and 1.1 x 10^12 cm−2, respectively. Superior performances in terms of a large memory window, long data retention, and robust endurance were observed.
