Leakage conduction mechanism of amorphous Lu2O3 high-k dielectric films fabricated by pulsed laser ablation

Amorphous Lu2O3 thin films have been deposited on p-type (111) Si substrates by pulsed laser deposition (PLD). A equivalent oxide thickness (EOT) of 1.16 nm with a leakage current density of 4×10−5 A/cm2 at 1 V accumulation bias was obtained for 4.5 nm thick Lu2O3 thin film deposited at room tempera...
