High quality interfacial sulfur passivation via H2S pre-deposition annealing for an atomic-layer-deposited HfO2 film on a Ge substrate

Abstract
The effects of interface sulfur passivation for ALD HfO2/Ge substrate were studied through the (NH4)2S solution treatment and the rapid thermal annealing under an H2S atmosphere.
