Al- Al2O3 interface study using surface soft-x-ray absorption and photoemission spectroscopy [link]Paper  doi  abstract   bibtex   
The local structure and the electronic states of a thin oxide layer on a single-crystal Al (111) surface has been studied using surface soft-x-ray absorption and soft-x-ray photoemission spectroscopy. Unoccupied interface states are found in the oxide band gap. The local structure of the thin oxide layer is compared with the structure of bulk Al 2 O 3 . The effect on the electronic states of an amorphous to crystalline phase transition is shown. The crystalline oxide-metal interface has fewer unoccupied interface states in the Al 2 O 3 gap than the amorphous oxide-metal interface.
